Quite confused. I remembered a suggestion about 127 (similar to the 131)
iSonic 127 : Deboichet R 16 slalom : 7,2/44 ; 7,5/44 ; 7,8/46 ; 8,3/46 ; 8,5/48 ; 8,8/50 ; 9,0/50 ; 9,6/52 ; 10/52
So 9.6 better with 52 (so I think even with 9.5).
Plus if I'm not wrong with choppy sea better be 2cm longer than normal.
Plus I know pro-surfers like to use 2cm less than normal.
I don't know the insandout skill, but I'm experienced but not pro surfer, so what is the real best fin?

Hi Emil

Is only 80 kgs and for this board with 9.5 in choppy water to control the lift he don't need this extra 2cm.

For full PWA slalom race who is down wind remember Cyril is using R16 48.

For customers who want also to perform in up wind need a bit longer ;)
hope this help

All the best
