I think those boards require the rider to be completely on it. Stand in the sweet spot( nose or the tail) and take full advantage of the waves
sweet spots utilize the way the board addresses the wave at every opportunity.
R. Kenvin is among my favorites to watch, I'm so inspired by his surfing and/or at his age to ride the boards he can ride the way he does. Totally efficient. I love watching surfers of high caliber riding boards that are unforgiving oddball stuff.
Many of us rode crazy thin and hyper rockered boards in the 90's, but not 2". As an average kid here locally back then, myself and many others made those ridiculous boards work so I'm not at all surprised to see talented surfers riding these, I dare say there's a lot to learn watching these guys ride the stuff, but I'm not the guy. I would never have a good day but it'd be fun to get a little. Learn a little, but times ticking away. But, look at RK?
