I have tried the 8m.great kite really a freestyler but hooked in kiteloops even super over powered are for sissies or learners.the kite turns over 45 degrees from the sea producing only upward drag and almost no horizontal.too easy like the RPM
Have you flown it on 20m lines?
Because in the beginning I had the same problem with the C4 (on 25m lines),
but later I bought a 5m too with a bar with 20m lines + 5m extensions.
When I use these 20m lines on the 8m, the kite is (almost) in front of me when I loop.
And I started with kiteloops in the beginning of the season ( 7-8 months ago ),
so there is still improvement in my loops
