I personally think the Rev is a bit of a dog, seemed to get over powered really quickly (I hae just demoed an 11m), EH rippers are really nice, fast to turn and fast through the window but with a bunch of depower available .
Also see if you can get a Takoon bar for whatever kite, i think they are they best available right now.
The Ozone are a great kite too, really well built and has the anti inversion setup which is good if you like to push the top end. (flown 9,11 and 13 - biggers ones were the 'sport', 9 was a 'lite')
