Hi Joe,
I'm 6'3" and 85 Kilos and I have paddled the 6'2" Airush Converse up at Exmouth in small 2-3 foot clean waves and it paddles in well despite it's small size (my normal surfy is a 6'6" Delta fish).
I can't comment on bigger surf, but I was honestly surprised at it's performance in such small waves and am keen to try it again in similar conditions to get a second opinion.
It's a good board for smaller waves and light winds say up to 18 knots, over that I ride the 6' Converse which is great fun, but too small to paddle ..... I think, maybe I should try it too!
Good winds,
