Does anyone know the actual playtest results of string tension on the more extreme ranges. I know that generally, looser string tension gives you more power but obviously you can't play with a net in your racquet. So there has to be somewhere in between where lower tension actually gives less power. So if you were to graph the different tensions how would it look like? High tensions, assuming that the string wouldn't break I think would have very little dwell time, low power, and an arm killer. Normal tension ranges would have a normal ammount of tension and power. Very low tensions would have more dwell time, less power, very arm friendly Another question to ask is what is a trampoline effect? I've heard of it mentioned but I do not understand what it is.And do higher tensions give you more depth control or directional control. Because I know a lot of people say if you are hitting long, just string higher, but couldn't you also string lower since it gives less power?
