Got my apacs Lethal 70 re-strung at 27 pounds. It has an isometric head. Unfortunately, it was strung at "27x27". The racket head was clearly bent out of proportion - it became significantly fatter and shorter. I'm getting it re-done at "25x27". That is, 25 pounds on the mains and 27 pounds on the crosses. Does this sound correct? I think it sounds right, as this would mean there is more tension pulling the racket head with "side-to-side" force. Another question I had was whether the "27x27" tension would harm the racket?
