I have 2 MG prestige pro, one is strung with Lux BB alu pwr rough 55 lbs and one I strung it myself w maxim touch at about 58 lbs. It was my second stringing job ever w/ a gamma x-2 and today i noticed the racket head is kinda deformed ( its rounder and the whole racket is shorter by 2mm). Its seems that the mains is pulling too hard that it makes the head rounder compared to the other one. I asked my hitting partner and he agrees that one is rounder and shorter than the other. But so far it hits fine.. I should mention that the lux was strung by stringer with one piece and the maxim touch is in two piece Am I exagerating or is it possible 3 lbs difference in tension could result in a slightly deformed head? Should I cut the maxim touch and try restring it again? Thanks for the help I really appreciate it!
