Head Velocity MLT Power String Review
With the 2024 release of Velocity MLT Power, Head builds upon the success of the original Velocity MLT, one of the game's most popular multifilament strings. True to its name, Head's newest multifilament is designed for the player who craves easy access to power. Judging from the scores and comments of our playtesters, the design works in spades, and it resulted in one of the highest power scores this side of natural gut. It also received exceptional scores for comfort and feel, proving wonderfully responsive on shorter strokes and volleys. Like most nylon multifilaments, Velocity MLT Power is no spin monster, and it suffered from frictional wear and string displacement as the test wore on. As a result, advanced poly players looking for durability and spin will want to sit this one out. Ultimately, though, if plush comfort and easy power are your top priorities, Velocity MLT Power will not disappoint. Did we mention the great price?

Final Verdict
Breakdown
Power: 9.3
First and foremost, Velocity MLT Power is powerful. Unlike a stiff polyester monofilament, this string is built to deliver higher ball speed with less effort. Although Michelle covets the control she gets from her ultra-firm polys, she definitely appreciated the softer feel and easy power of this multifilament. She said, "Let's be transparent from the start; this is a multifilament string and I am a poly player. I wasn't expecting this string to magically have poly characteristics, but I also welcomed the chance to hit with something softer and more powerful than my normal string. With that said, I've been teaching a lot more lately, and I find multis to be good for that because I don't always want to work so hard to achieve depth. Velocity Power proved awesome for coaching and hitting lessons. It was soft and plush at contact compared to the normal boardy setup that I use, and I loved it because it didn't have that 'pingy' sound or feel that I find with a lot with multis. Control was good for a multi, but there certainly wasn’t as much control as a poly. I also loved hybridizing this string, specifically with Lynx Tour. I thought it brought out the best qualities of each string — comfort with control, power with access to spin, and a bit more durability than a full bed of Velocity MLT Power.”
"I could control the ball and still get very easy power without having to work hard for it."
Like Michelle, Troy is also a poly user, but he too was able to find a groove with this powerful multi. He said, "I would say this string packs a good amount of energy return. I typically play with a full bed of poly, so I knew what I was getting into, and that's partially why I put this string in a low-powered 18x20 player's racquet (the Head Prestige Pro 2023) at a slightly higher tension. Compared to the original version, Head Velocity MLT, Velocity Power did indeed feel slightly more elastic, and I could generate a bit more zip or zing on the ball. I can't say I have any quantifiable data for an increase in ball speed, but it seemed as though I got a little more pace on my shots. I definitely noticed the increase in energy return compared to my usual poly setup, even with the increase in tension. I typically prefer the control of my full poly stringbed, but I appreciated the increase in power on my flat serves. I felt like I was hitting those serves with some extra juice on the ball. Also, once I dialed in the launch angle, I felt like I got good pace and easy depth on my slice backhands."
Spin: 6.5
Although Velocity Power is not a polyester, it still gave our crew enough spin to bring the ball down reliably, especially when tensioned high enough. It could produce the required level of control for maximizing stroke speed without having the ball slip out of its trajectory and sail into another ZIP code. On the downside, its surface wears down much quicker than a poly, which means it gets stuck out of position rather than boosting RPMs by snapping back. Troy had the most success with this string on slices. He said, "Like I mentioned above, after a bit of adjustment I really enjoyed this string on my slice backhands. I wouldn't say that I got as much bite on my slices as I do with strings like Solinco Hyper-G or Head Lynx Tour, but I was still really effective at keeping the ball deep and low. It had a slick coating, and for the first few hours it pocketed well and the strings slid well on top of each other with decent snapback for a multi. However, after the first few hours the slickness of the surface and the resulting snapback weren't quite as good. I would say my biggest knock when it came to topspin potential was just that lack of grab on the ball when I really needed it. For long strokes, when I had the time to make some adjustments and sort of accentuate the low to high brush on the ball, I found the topspin to be OK — not ideal, but at least I could adjust my stroke to get the arc on the ball. But when I needed that bite on the ball to get it up and over the net with a flick of the wrist (think whippy topspin shots), I was struggling to get that easy grab on the ball like I get from a shaped poly, like Head Lynx Tour."

The spin wasn't great for Michelle, but it was sufficient for getting the job done. She said, "I thought Velocity Power had decent access to spin for a multifilament string. I tend to not need a lot of spin from my strings, and when I noticed less spin than I get from most polys, it was mainly due to the ball floating out just a bit, which was a result of Velocity Power being more powerful and having less access to spin. I never once felt like I couldn't hit with spin, so no issues here."
Feel: 9.0
In addition to power, the other standout features of Velocity MLT Power were the comfort and feel. Michelle was impressed that the soft and arm-friendly construction didn't come with a mushy or disconnected feel, which is a common downside of multifilaments, especially as they lose tension. She described, "This string was very soft and comfortable without ever feeling mushy. It pocketed really nicely even at higher tensions. The feel was really nice, and I didn't have the 'pingy' feel that I tend to notice with many multis."
"Overall, Velocity MLT Power felt very plush and pocketed the ball very well."
Although Troy typically plays with stiff polyester monofilaments, he couldn't argue with the comfort and pocketing of Velocity MLT Power. He said, "Feel and comfort were top notch! When it came to the ball pocketing and the overall comfort on my arms, I really had no complaints. The comfort level was pretty much right up there, and I would say it was close to the premium multis in terms of comfort. In terms of feel, it was a little on the muted side. I didn't have quite as much feel for the ball with Velocity MLT Power as I do with strings like Tecnifibre X-One Biphase or Gamma Live Wire Professional."
Playability Duration: 7.8
Velocity MLT Power holds its tension better than the polyester monofilaments our playtesters typically use. However, according to Troy, the surface succumbed to frictional wear toward the end of the playtest, resulting in some issues with snap-back and spin. He explained, "In terms of the tension maintenance, this string held up well over time, especially since I mostly play polys that tend to bag out more quickly. I would compare it pretty closely to the standard Velocity MLT, but maybe a bit better over time. Compared to the multifilaments that I have tried, this string is average to slightly better than most. I guess if I had to knock this string in terms of playability, it would be based on what I mentioned earlier about the slick coating and the snapback of the mains on the cross strings. I definitely wouldn't say this string was super 'notchy' or sticky like a lot of multis can be, but it wasn't as slick and spin-friendly as time went on. I noticed the string getting less spin-friendly after about three to five hours of play, and it decreased gradually after that."

While Michelle wasn't blown away by Velocity MLT Power in this category, she was satisfied with its performance. She said, "I noticed I could get a few solid days out of this string before it started notching a bit. I was happy with the durability, and I know these won't be as durable as the polys I often have to cut out. It was great in a hybrid, and there were no issues with durability when used with a poly."

Playtester Thoughts

Michelle
Velocity MLT Power is such a great string for players who don't break strings and are looking for an arm-friendly option! At a great price too! I think I would recommend this string to many USTA players who are looking for a bit more free power. While I don't think poly players will want to switch to Velocity MLT Power, I do think it’s a solid option to hybrid poly with! I'm not using multis as often as I’m using polys, but Velocity MLT Power definitely has a feel similar to Tecnifibre X-One Biphase, and will give you a similar experience. You can also expect more power and comfort compared to the standard Head Velocity MLT.
Soft, comfortable, easy power, no pingy-ness. I love using this as my string of choice when coaching and teaching! Also, I get really nice comfort and response in 18x20s.
Velocity MLT Power started notching after two or three days. It has less control than a poly, but that is to be expected.

Troy
Compared to the standard Velocity MLT or Wilson Sensation (I guess you could say the two best multis around that $10 price point), Velocity MLT Power felt more elevated, with a bit more power and a very nice plush feel. That said, when I started to compare this string to the premium stuff, like Tecnifibre X-One Biphase or Gamma Live Wire Professional, I noticed that it felt a bit muted and didn't have quite as long of a playability duration. Compared to my usual strings, like Head Lynx Tour or Solinco Hyper-G, there was not as much bite on the ball, and I didn't find the very dead or low-powered response that lets me take massive cuts at the ball. However, there was much better comfort, feel and energy return compared to my go-to polys. I think Velocity MLT Power is a great option for players who want the comfort and power of a premium multifilament, but at a better value. Comfort and power seekers should love this string, and especially players who want to soften up the feel of a stiff racquet. I would also recommend this string as a good option for those who want to hybrid with a poly (I usually recommend pairing with a round poly rather than a shaped poly for durability reasons).
The comfort is top-notch, and I got a lot of energy return. There was a good amount of slickness and string snapback for a multi in the initial phase of testing.
There were times when I craved that extra bit of bite or grip on the ball that I get from my usual shaped co-poly strings. After the initial test phase (about three to five hours), the string slickness and snapback started to diminish.
