I also agree you can't please everybody with either 1 stock fin or with 2 stock fins. I use 3 or 4 fins for each of my boards, mostly depending on the conditions and sail size. The choice is even greater with a crossover board that can do wavesailing, freestyling or freeriding. One can choose many best-in-class fins for each of the 3 programs above or one can choose a single do-it-all crossover fin. Good news is that the current market is almost without boundaries for the customer. Bad news is which one to pick up for your own taste/skills/setup without first hand testing. Forums like this one are a wonderfull place to start your upgrade inquiry and to please almost all customers.
