First session with my new KA-sails and as expected I can easily handle a smaller sail in comparison to my buddies. 6.6 was a little big at times but did'nt had the time to change to 5.8. The 30 cm fin was a little smal for the combo, had have taken the 34 UFO so have to experiment a little bit the get the right combo. Nevertheless I very nice feeling (lightweight) sail that gets the board very early planing capacities and lots of power!!   Trimming is very easy and can be done in the water, have changed the downhaul twice (little more due to increased winds  and no time to change..) so am friends with the sail already.
