Sonntag SL-P 40cm
Bought 2nd hand over the internet in December 2013.
I was looking for good modern Slalom fins with little twist and a lot of tip flex. The Sonntag fins are well known for this.
As always, this Sonntag was measured in the factory and this fin has the following bending curve: BS56FT30%
Rake: 10.5&y;,here more info about Sonntag bend curve specs.
I think the tip of the fin is soft, but not as soft as the Boss fins.
The SL-P doesn't seem better lowwind than the Boss, the Boss a little better high-wind.
With the iSonic 122 a perfect fin for the 7.8, With the iSonic 117, this fin seems just too small.
With the cleaning up of my hard weather slalom stuff sold this fin
