what's in your opinion the most agreable board (2010) for this sail size? ..and why?!

my needs:
-super choppy condition and steady wind (always used the 6,3 but often asked myself if smaller was the case!)
-flat water/off shore wind,super gusty (fighting with the 6,3 and killing my arms because wind can be 10-35-4!!)
