I'm 73kg and have a '14 JP96 All Ride, love that board!
I use it in head high surf (average), with a 24cm surf fin, and flat water ocean conditions with a 30cm free ride fin (stock), couldn't be happier.
It has the option of dual rear foot straps and more of an outboard position for the front foot straps, for smooth flat water, racing around, but I've never tried it in those conditions yet, but I'd like to someday. I use it with a 5.2 or bigger (only), it's very similar to Vince68's setup. It's my light wind ocean board.
