My NSR (185/14-17m/20cm) instantly made me a better carver. I put a Donek AF plate on it to see what the fuss was and notched a couple of levels up again.
It's my go to board when I want to rip cord on wide open steep runs. It loves it when you jump on it's nose and tell it to rail.
Like Corey said somewhere else, it doesn't like skidding around, but when I ask it to carve, it tears into groom at much higher speeds than I'm comfortable riding.
