Been playing with Prince syn gut.. was using a bunch of different polys mainly because of the durability but I play much better with syn gut. May have to venture into multi's but that's another topic. Was stringing my Prince Diablo XP OS racquets at 62lbs with prince syn gut but today I decided to try it at 55lbs and loved it! I think I could even go lower.. just curious, how low have you guys gone with prince syn gut, or any other string that isn't a poly?
