my friend has the single fin,its pretty sick and comes out pretty easy but it isnt sealed that well. they basically took a finless board and poked the holes in it to put the fin in. they dont slide out very much and it helps for pumping but im used to riding my herlihy stand up so that might be why its so easy for me. they bend pretty easy too and can get some creases if it gets worked hard enough. pretty sweet all around though.
