I have read all of the threads about a lower tension string will give you more power because of the trampoline effect. I have also read that a higher tension will give you more control and power because it runs across the string bed more. I agree with most of this. The part I am unsure about is the higher tension giving more spin. Logic seems that if the lower string tension flexes more and gives more snap on the side of the ball it would make it spin more. The reason I believe this is because I used to use 55pd and I would get a lot of spin on my cut shots and my slices. I could drop a ball right over the net and it would die. I could return a weak serve and spin the ball low and away from the server in the alley. I went to a spin friendly racket but put the strings to a higher 59pd tension. I don't seem to get the spin/cut/slice effect like I once had. I went back to an older racket that was still strung at 55pd and I started getting these shots back. Was I mistaken on higher tension gives more spin? I wanted to get others thoughts on this and see what works best for other players who also try for spin but use high or low tension.
