Kelly's cutbacks always look really good. Full stop.
The board itself doesn't look like it has a lot of drive but that doesn't seem to bother Kelly. He's really good at generating speed. Same kind of thing that screwed us mere mortals in the 90s, rockered out boards without a lot built in drive surf great if you have the ability to generate lots of speed.
He is super slide on that board. Never been a wing person, although I LOVE the looks of them - always frothed over Arhcie's double wing swallow tails. Front fin at the wing really does produce a different look; opens the tail up for more push, for sure.
