I've been stringing Cyber Flash / Hexy Fiber at 48/53 in a low power 95" racquet. The 5 lb. diff. is because the Hexy Fiber is very soft and I like it to stand up to the poly. If I were stringing for someone else, I would go up 3 lb. on the multi cross.
I'm proud to report that my hi-lite reel beats my outtakes by a wide margin.
