I'm not too fond of F-One as well....
I keep real good care of my kites, check them after a few sessions for pinholes etc, but my Bandit 3 11m tore in half after a pussy crash. Had it fixed, and 2 months later it tore in half again, but this time on the other side!
Had a Bandit 4 8m as well, and that one tore in half as well
Had the depower rope (with that indestructible PU tubing) replaced twice in 1,5 year because it was eaten by the bar. And I always dip my bar in the water before kiting, and rinsed it after the session with fresh water.
The pulleys on the bridles had to be replaced once on the B4...
Got an Acid 2012, had to replace the fins once and the bottom isn't really scratch resistant... Ok that's my own fault as well ofcourse, but didn't have those issues with my older Naish board.
And I know some guys who have their bar grips completely molested...
Nah I'm done with F-One.
