fin size for NP 9.8 on isonic 133?
I'm wondering whether the standard 48 drake fin with the I sonic 133 is big enough when using my NP V8 9.8 on the board. Broad reaching is ok, however going upwind results in many spin outs, regardles of changes in footstrap position. I weigh 104 kg's, 1.99 m tall and subsequently use the IS 133 with the 9.8 when many other sailors are down to for instance 7.5's, so a lot of pressure on the fin.
In the 2008 catalogue I see that for the " new" Isonic 133 also 80 wide the recommended fin range has expanded upward. So now I'm thinking of a Select gold 56 or something along that line. What to do?
