In my experience, I have found the 15' profile with a 1" radius of hollow to be what works in many areas of my game. Crossovers feel stable and straight-line speed in the low 20 miles per hour. Cutbacks, edge drags, and other dekes feel balanced and controllable.
Profiles I have game experience with:
15' - ROH 1"
Cag One 30-55 Pitch(1/2" Back from Center) - ROH 3/4"
ProSharp Detroit 2 13' - 26' - ROH 3/4"
ProSharp Quad Zero 6'-9'-11'-13' - ROH 5/8" & ROH 7/16"
11' - ROH 1/2", FBV/Blademaster X7, & ROH 1"
ProSharp Zuperior M 6’-13’-20’ - ROH 3/4" & ROH 1"
Maximum edge 981 - ROH 5/8" & ROH 1"
Double radius 8' 12' - FBV 100/50 & FBV100/75
