Hello Dimitri,
Just got back from SA, tried your kite the weekend. It is truly unbelievable !!
I rigged it on Lake Houston. Wind range between 6.5 to 12 miles, the powering and de-powering toggles works beautifully and put not strain on your hands while adjusting this in the ride.
I have a few cuts trying to adjust the 14m Cabrina, so well done !
I will try the board this weekend, well done for designing something so great !!

Regards
Derek
