dontknow Hi Rico, the issue with the more forward placed fin did occur mainly for the bigger size FreeWaves, mostly for riders with a bit more back foot pressure/shorter lines etc - most of them could adjust their style somewhat but of course there will always be people who do not want to and prefer a board which is more similar to their older boards/other boards on the market - that is their choice of course and we accept that.
But anyway the newer Freewaves combine elements of the older and newer STB versions, for a better Freeride and Wave performance- narrower nose and tail outlines, flatter rockers on the bigger sizes etc. So the standard fins are fine, you can also use up to a 30cm fin on the 105 if you like.
