Sonny, is there a specific brand or type of fin I should look for because the board does not come with one?
well u need a Phd is fins to find the fin if want to understand everything or u can jump on fin manufacturer "fin chart" and get a rough idea, then check second hand stuff ..also ask questions on the board manufacture and its forum...usually the board forum is the best place to get good advice on the fin ..
link to select fin selector...
