The first choice for me so far is Wilson 16 Natural Gut Mains with ALU Rough 16L Crosses, the Wilson Champions Choice package. Mains 50, Crosses 48.
This comes after several experiments with full bed premium multis like Xcel and NXT as well as full bed Wilson and Pacific gut.
Lots of power and no fraying at all so far I think because the ALU is so slick everything slides easily. Also the mains are always snapped back in place for the same reason.
Your mileage may vary, batteries not included.
