Hey everyone, I must admit that I have probably only read 20 something pages out of the 66 in this thread, but I hope you will permit me to post anyway. I just wanted to share a humorous personal Velocity anecdote...
I've been a poly user for a few years now (I'm still pretty new to tennis, so essentially for as long as I have been serious about playing), but my wife recently had per racquet (Pure Strike 16x19) strung with a full bed of Wilson NXT 16g, and I thought it felt really, really nice. So I bought a pack of Black Velocity 17g for my own Pure Strike 18x20, because the Velocity was cheap and I like black strings. Somehow, however, in the time between getting the velocity and actually using it, I made a racquet switch.
So fast forward a few months and I'm really enjoying my Vcore Pro HD, but only using poly strings to this point. Then I find this thread and that pack of Velocity I have lying around is staring me in the face! So the next time my poly goes dead (which is a feeling I hate), I head over to my local stringer and drop off my racquet to be strung with the black Velocity 17g at 51lbs (my poly tension was usually around 47-48 for the Vcore, and I wanted more power). He wasn't there when I dropped it off, so I left it with his wife, who dutifully took note of my preferences.
Well, two days later I go to pick it up and he starts giving me a hard time. I like my stringer, he has personality, and he isn't afraid to share his opinions (part of the reason I like him), so this wasn't exactly something new, but he was a little more vehement than usual. He said, "I strung it up for you because you bought in the string, but otherwise I would never have strung your racquet with this string." I asked him why, and he pretty much just said a few times that it wasn't the right string for me (English isn't his first language, so maybe he couldn't quite articulate his exact thoughts on it). Suffice to say, as I offered up my usual 'see you later,' while walking out the door, he replied with a very deliberate and wry, "see you soon," clearly in reference to how long he expected my Velocity experience to last.
And how has that experience been so far? Well, it's still a little early to say. I've only have one practice session at the wall, and one 1.5 hour doubles session to go by so far, but generally things are positive. The feel is pretty great, spin is just fine (very comparable to polys), and I haven't had too much string movement. But the power is noticeably on the low side. Nothing awful that I shouldn't be able to adjust to, but certainly noticeable. I guess the biggest question is over durability, as the strings are already feeling slightly rough/frayed to the touch (oh, I should also mention that they felt SUPER slick when freshly strung. As if they had a coating of oil or WD-40 on them). So let's see how they hold up. As for my game, I do like to hit hard at the wall, but in doubles find myself hitting more for accuracy than power, and as I mentioned I'm using an 18x20 Vcore Pro HD, which in theory should help a little with longevity.
