Hi everybody! I wanna ask you about the appropriate strings for me... i have been playing for several years, i have enough control but not too much power because i'm a little skinny... I play with a Wilson SixOne Team, 10.2qz/289gr. and 55 lbs/25 kg of string tension. How much less tension should i get to hit with greater power, without losing control? 2lb, 4lb, ...? Thank you! See you guys!
