Being plagued by shit waves this summer I reached deep to build a micro ripper. Polyurethane blank with Resin Research Kwick Kick Epoxy.
5'4 x 19.25 x 2.25
This one is small but had enough foam hidden to keep it easy. I would say order one of these 5 inches shorter than your HP shortboard. I went a little shorter as a experiment to see how small I can go and not be struggling.
