I actually I ment to say in my previous reply that I do indeed depower the 17m when riding in light winds then fully power up when it picks up and start to depower again when it picks up even more. I used to do this with my old kites years ago.
I assume that the kite is aimed at race boards so performs with big directionals where the kite can ride right up at the edge of the window but when you combine it with a twin tip with the extra drag, the kite flys well forward and looses power so you pull the bar to get that bit more and you upset the balance. The old Dyno did this easily and kept pulling, easy as!
I was racing my buddy and usually could hold my own upwind, reaches etc when I used the 18m and Sector. When I take my 17m, he pulls away from me on the upwind legs and evenly matched on reaches. My buddy is on a Sector and 16m Dyno. Grabbed the 18m again and it was even again.
Looks like for me to get the best out of the 17m, I'm gunna have to change my style. I don't mind the kite in strong winds but it isn't as fun as the 18m. I really wanted it to be better but in my opinion it isn't.
