I am finding that I get a lot more control when my racquet is strung at a lower tension. Is that normally the case? This defies what I used to believe was true, (lower tension = more power) and (higher tension = more accuracy). My understanding is that with a lower tension the player would get more of a trampoline type effect that would promote power. I imagine that with a lower tension the ball would be in contact with the strings longer therefore alllowing more control. I currently play w/ Babolat Pure Storm GT racquets, which have a suggested tension range of 55-65. I most recently strung one of them w/ Wilson NXT 16 @ 55 lbs, which feels pretty good, but I'm tempted to go even lower. I read somewhere that to get "optimal performance" I should be stringing that particular model at 60 lbs. What do they mean optimal performance? Is there more to this than personal preference? Is it common to string below the suggested ranges?
