I just replaced a 2016 KA Koncept with a 2019 version. I never use the printed settings for the 2016 sail, because they just don't seem to be right. To my surprise this has changed for 2019. The printed settings seem to be spot on. I don't know who provided the input for these new settings, but does this legend also have a list of his 2016 settings that he/she is willing to share? The remaining 2016 sizes in my quiver are the sails I don't use that often, so accurate settings would help me a lot.

Last Saturday I used the lower clew eyelet for the first time. This gave so much control that it almost felt like a sail one size smaller. Great for overpowered conditions when there is no time to rig a smaller sail, but it made me wonder what would be faster: smaller sail with upper clew eyelet or bigger sail with bottom eyelet?

For anyone involved in the R&D for these sails: thanks! Great sails. One of the best freerace sails I have ever had. Race sail stability with enough power for mere mortals. Sails are equally happy to be used for some relaxed light wind cruizing as they are for completely overpowered blasting. The 6.2 2016 Koncept on a Futura 93 is one of my all time favourite combo's for a nice burn&turn session.
