Deboichet SL4 + is101
I would like to ask you what are the differences between SL2, SL3 and SL4 fins?
If I got it right, SL4 is proto fin that you used in PWA 07 races?
I have isonic101 2007 + SL2 36 for TR4 6.6. I would like to go for 2 more fins, one for 5.5 and one for 7.6. Which fins do you recommend? My weight is 75-80kg.
By the way, what is the biggest fin and sail that you used on is101? How did you like it?
