I had a try today with the fuel 2010 11m (I usually ride a hadlowpro 11m, mostly freestyle).
I've found the kite really predictable, the turn, acceleration, power...everything come smoothly. no instant surge of power like on AHpro. the fuel deliver slightly less power too, but have a really better depower.
I've found handlepasses easier with the fuel, but the pop is better on AHpro, because the fuel isn't enough stiff to really transfert the power through the lines, mainly in light/moderate winds.
Kiteloop are impressive on fuel, the kite create a big curve by itself, and really accelerate during the loop, the AHpro don't do that, it's more constant, but the loop is harder to finish, like a bigger kite (because it's more powerfull, so it's logical)
Jumps on fuel are very good, better than on AHpro, you can really take high jump without concentrate too much on the kite.
The AHpro has really an efficient profile, but will you have enough skills to exploit it ? and the fuel is more a forgive c-kite, smooth but perform well, easier to land actual moves.
For the future, I'll certainly go for a 8-9m fuel, but I keep my 11m AHpro for light wind freestyle.
