In my experiences a softer rail board works best, as there is less chance on catching a rail and falling. Also I find a moderate sized square tail works the best, easy to pivot turn and to catch waves. You also want a moderate board width, if you go too narrow it will be way to tippy, to wide you'll find it a lot harder to manoeuvre . My favourite board for bop is the Starboard BOP race, as it has all of the above in my opinion. As for paddles everyone seems to use their D/W paddle :) Now fins, most of the guys use a hatchet style fin, theres a few of these on the market, like JM's signature one. I hope this helps, Lincoln
