Phantom 320 fin?

[blugroove]

Hi, I have the 2007 model phantom race 320 with the 48 cm drake sl6b fin. I use the board mainly with a 9.0m2 freerace sail. Do you think that moving to a bigger fin (r13,r19 54-56cm) could make the board plane upwind? If the wind picks up its easier for me to planeupwind instead of getting on the rail.
