Simonm, it will interesting to see how you find the kima's, especially the 6m.
I remember from past threads that you and I used fuels on short lines in the past.
My favorite wave kite was the 8m octane from 06, until I tried the 6m kima.
What we want to do on waves sounds similar, though the conditions I ride in most, don't really suit unhooking.
I used to find the 5m Diesel to on and off for gusty 15>>>35 knt wind, but the 6m Kima will get me upwind in 15knts, and handle 35knts as well.
So give the 6m Kima a try.
I know Felix is riding one on a fixed bar, unhooked , and it seems to be working in 15>>30 knts for him.
But hey , if you still prefer generators, so what ? that's the beauty of this sport, so much to choose from.
