hello guys, ive been at these forums a lot but havent gotten around to posting. anyway, i was wondering if i should switch to a higher powered string/less tension or to a lower powered string/more tension, since i do not know if i hit too hard to too soft.. here's the predicament: on most of my shots, i usually swing as hard as i can, and when i hit it right the ball goes off with good pace but it bounces within my opponent's service box... which is too short. however, when i try to aim deeper, the ball just goes barely out. i want to hit it so the ball bounces beyond the service box line WITH good pace.. is this because my string is too weak or too strong? i know with better technique i could do what i want, but if i could restring my racket at a better tension to aid me, then i want to do so. i'm a ~4.5 NTRP player and currently use a PDC with NXT tour strung @ 62 lbs. thanks for any help!
