Don't go lower on the Wilson gut. It's the new Babolat gut that gave you most of the problem. They made it stiffer and lower powered to be used in hybrids in the low 50s. From what I've read, Wilson gut is pretty similar to the old VS. Because you have a more open pattern now, you may want to go up on the tension by 2 lbs., or keep it the same as your old VS.
