thanks PG. to be frank I did check boards, and found so much info in there that got a bit confused. just need a straight advice on this specific board. i read in a post from Ola that the vertical of reaar tip of the side bites should fall some 32 centimetres from the tip of the board. also on which fin system, some seem to suggest i go for Probox but I have doubts since probox doesn't seem to get to the udnerside of the board (the deck).
but as you say there's a real treasure there, maybe I should take some time and study the whole thing.
