Sturdy and convenient
So much better than the glued-on (and easily glued-off, in the heat) fins of previous compact boards. To improve sturdiness even further, I'd make the lock-pin in metal rather than this dry plastic which, in my case, has snapped twice. Very happy that Red Paddle sent replacement pin promptly and at no cost. In the meantime, a standard (metal) hairpin, does the trick :)
