I have been playing a year and I have been using the Wilson Pro Staff Rok 93 strung with Babolat Tonic ball feel (16) at 53 lbs. I am thinking of going to 57 lbs or alternatively to use hybrid, natural gut for the mains at 57 lbs and poly for the crosses @ 53 lbs... What are your thoughts on that? I would like to gain a bit more control without sacrificing much power. I have been avoiding any kind of poly because of the fear for possible TE... PH tour 125 (17) with VS natural gut 130 (16). Should poly and gut have the same gauge size?
