Deb SL4 stiffmess 2
I have bought 30cm & 34cm SL4s for 2009 ISonic 94, 86 & W53.
What rigidity are you using - rigidity NR 2 stiff or flexible rigidity 1?
What differnce is there betweeen them when sailing?
Have you tested the SL5 any more is there any time they are better?
Designed for rough water & strong wind?
