iSonic wood carbon 121 fin
I am a team rider of 70kg. Just received my new 2010 iSonic 121.
Will sail with 7.0, 8.0 (moslty) and 9.0 with this board.
I would like to buy a Deboichet custom fin (maybe 2).
The SL4 is recommended but I heard that the SL2 may be better. Which one would you recommend and which size ?
