Hi! This is my first post here and I hope it's okay to ask these questions in this category. First, I noticed the Catapult 10 is half price, is this a temporary sale of some sort? I'm planning on getting one, and I want a lot of power. My previous racket, a Catapult 7, was sadly broken in the heat of battle, and I'm thinking the Catapult 10 might be a good replacement... but this is the thing. When I demoed the Catapult 7 from a local shop it was full of power, but when I bought one and and tried several different strings I could never get the same feel... but at the time I demoed I didn't think to ask the string or tension. So what string and tension would give me the most power? Of course I guess lower gives more power, but to what point? I have one more question. I seem to be very sensitive to grip size and I can't figure out how to get the right grip size. I keep making it a little smaller and a little bigger, and it never feels right. Bigger gives my hand callouses, smaller makes the racket turn. Once, and only once, I got the perfect grip size, but even after measuring it, I couldn't seem to reproduce it when I had to change grips. What are the thinnest overgrips sold here at TW? Do you have any ideas for my grip dilemma? Maybe it's my grip that's wrong? Any reply would be appreciated, hope these quesions are ok. :?
