Yeah I have asym 6-8 PU and sym round 6-6 in XTR 8.c.Only been on sym. It works. I believe Ruka had both
Both are really fun and if you only go frontside I think asym is nice, especially for longer lengths.
I prefer sym round tail for my situation. Prob one of the most versatile boards in my quiver. No issues digging the nose in tubing waves. I'm usually angling a bit on takeoff and trying to get in early which the board does well.
