Since you did this testing of the Futura 122 wc , which I`m wating for, I hope it`s all right that I ask for your advice of fins to use on the board.
I`ll be using 5.5 - 6.5 and 7.5 nocam freeride-sails (Ezzy)
42 stockfin will match the 7.5 i guess but what to go for down from there?
75 kg advanced!
Did you try more sweptback fins on the board?
