yeh ste, last two seasons, dice before that, but i'm on old school board off type tragic so the rebel works well for that, and some pretend stuff in the waves on a TT.
Wouldn't mind a smaller dice for looping though...The rebel 10m gets a little scary looping in 25 knots..lol, scary in that the loop is pretty soft and you wonder half way around if its gonna pull you through or not!!
Yeh man recommend trying both kites. Try and get on the boost 11m if you can I reckon to really work out it's boost and hangtime potential in 20-25 knots. 9m is always too small unless you are at 25-30 and the hangtime is never there in any kite for anything but a basic big boost.
it's why a run a 10m rebel, can still do board offs in 25 knots and have that extra float for hopefully landing it...

always a trade off whatever you ride.
Hence, if you ever read hype about a kite that 'does it all'...run for the fckn hills. What one gives, the same design will take.
The boost is worth the time to try for sure, to see if it suites. it will come down a feel thing as the kite itself is good as any.
