Dave, Marty here, I measured that starboard carve fin you thought you could put to use which we talked about on tuesday. Its a 42cm wave fin with two mounting bolts. Any good to you?
I am speaking from my own 95kg belly ballast perspective here Dave - It comes in useful to hold onto the 6.4 when everyone is scrambling for their 4.7's and you can't be bothered changing down!
altho that 101 jp freestyle wave was much more your board mate!!
