I recently picked the game back up after a 7 year layoff about 4 months ago. Went through the demo process and settled on the Fischer M Pro 98 SL. I have been using Wilson NXT 16 gauge strung at 52. I went through the strings in about 5 weeks. I restrung with the same string and am already seeing significant fraying after about 3 weeks of play. I have topspin forehand/backhand, pretty big kick and flat serve. I am rated 4.0. Can anyone recommend a high quality string that will last longer? I really would like my strings to last a couple of months and not once a month.
