Thanks, CJC. Like you, I also cap my poly tension at 52lb. I was actually very curious about s.gut/poly hybrid that you mentioned. I will give it a shot with my Forten Sweet 16 and Cyber Blue 17 I have at home, at 55lb/52lb. It'd be fun to compare with the more typical poly/s.gut set-up.
I'll wait for my n.gut/poly to snap, and then move on to the same set-up with thicker gauge. I plan to retain n.gut/poly set-up for my main racket, and experiment with s.gut/poly for my spare.
Just curious, what strings and tensions worked best for your s.gut/poly set-up? From my distant memory I recall reading on these forums that s.gut/poly hybrid can be quite string-sensitive.
