dont bother using your regular surfboards for a start, especially in the beginner stages. I snapped two boards, ripped out FCS fin sets and made a mockery of it all.
Especially when you start to get some air, your average surfboards dont like your full weight landing on them especially if its your front foot.
In shallow water as soon as you hit the sand, you will loose a fin at best, the whole fin box, or snap your tail off.
i bought a 5'10 quad designed for kiting, thick stringer, double layer 6oz glassing, strap holes with pads, and future fin boxes. its heavy in the hand but sweet in the water, havent had a fin or snap problem.
hope this helps
