Favorite in quiver. I am 6'4' 190 and ride a 6'1. Definitely can ride this board a few inches shorter. This is due to the board being slightly wider, as well as being a little beefier in the nose than a standard shortboard. This gives it more speed and better performance in smaller mushier surf. Not a crazy amount of rocker either. In sum this board will be shorter, wider, thicker,and flatter than your standard shortboard.
I typically ride this board from a little above waist to about head and a half.
