Which would be the better size for a 98 mm waisted ski: 115 or 95 mm?
You could go with either size as the 95mm brake could be bent a bit to fit the 98mm waist and the 115mm brake wouldn't be too much more either. The cleaner fit would be the bending the 95mm size brake though.
I would go with the 95MM brake, the 115mm might create to much drag on your sidewall.
