I bought the pro stock version of this racket, and it came customized. The specs were: 310 wt, 31.0 bal, 295 sw. (I knew it had lead under the bumper and silicone).
But something didn't feel right, at least that's how I felt. I felt like it was missing weight, but I didn't want to add any. I felt that with those specifications, my forehand shot was becoming “loopy,” not the launch angle, but my style of shot was becoming like that for some strange reason. So I wasnt feeling my shots were great or feeling good about them.
So I started researching the “stock” specifications of this racket and what people liked about it, and I wanted to see if I could modify my pro stock and find what was best for me.
I figured I had to start with the balance, to raise it to 32.0 (strung and with overgrip) by removing the silicone, which without stringing was probably around 32.7 or 32.8.
I intended to remove the silicone from the handle, so I opened the butt cap and found that apart from the silicone, the oval thing you remove or pop out from the buttcap, had integrated weight (like the Solinco kit). This little thing alone weighed 9.7 grams, so I removed it and put another oval thing from a regular stock racket (which weighs 1 gram).
I tried it out, and for me it was a DIFFERENT racket. It really was what my strokes were missing. The new unstrung specifications were approximately 301wt, 32.7 bal, 294 sw.
After changing the specifications, I started looking for the right string:
I've used these combinations:
1) Full Head Hawk Touch 1.25 at 50 lbs: It feels very comfortable, the spin is average, but it has power and I feel it goes very well with this racket. The ball pocketing is also very good.
2) Hybrid Hawk Touch 1.25 50 / Toroline Truffle X 54: Super mega comfortable, the spin is less than average, lots of ball pocketing, but for my arm, (i have TE), it's the best combo.
3) Hybrid Solinco Hyper G 1.25 50 / Hawk Touch 1.25 50 lbs: This is the best combo I've liked. The response from the racket bed is incredible, the spin is the best, and the feel when hitting is incredible. The only problem is that my elbow gets very sore afterwards.
4) Hybrid Toroline O-Toro Tour 1.23 / Truffle X: For some reason, this combo is very good, but has above-average power and spin (not spectacular) but I didn't like it because it made my wrist a little sore (very strange), but it's a very good alternative to the Solinco Hyper G.
Next combos to use: Solinco Mach 10/Hawk Touch and Toroline O-Toro / Hawk Touch
However, for me, this racket needs a slightly “stiff” string on the mains and something soft on the crosses.
