As suggested try as many as you can. I have a guy in Byron make my sup/mal fins for me and we have had a fair bit of success with a fairly basey 9inch with a fine tip and nice progressive flex throughout the fin (on bigger boards) If you have mates who ride mals ask around and see if anyone has a redline fin or a greenough style fin around the 9ish inch mark and give them a try and see how they feel for you. IMO you really need to keep a nice wide base to the fin for drive but can pull heaps out of the fin tip to keep it coming off the top nice and easy without bogging down. If you try something you really like but can't buy one pm me and I will put you onto someone who can custom make a fin for you at better than shop prices.
I spaced the redline fin Wiz makes for McTavish - great fin
