Well I read about how most people string their oval rackets at X+2 by X in order to keep the head of the racket from getting deformed. I was wondering if this applies to isometric racket heads as well (and yes, i did do a search on this). Thanks~

Please read the artical by Kwun. The rule of thumb is to string cross 10% higher than main or x lb for main and x+2 for cross. For tension higher than 25lb, try 10% or 3lb more for cross. Same for iso racquet.

Good luck and have fun.
