If you are into wakestyle, or new school kiteboarding. Go with the Fuel. It sits a little further back in the wind window for a more consistent pull then the Octane does. I personally ride Fuels and ride them on a pulley bar. My style is a mixture of both becuase the Fuels can still jump pretty damn high.
If you are looking to jump to the moon and get nice floaty jumps, choose the Octane, hands down the higher jumper.
You can check them both out here at :

If you have any more questions about any of these kites, please let us know and we will be happy to help you out.
We also currently have a sale on all 05 Fuels that you can see here:
