It depends what you want it for...
wakeboarding, gusty winds, light winds, strong winds, jumps.
The only time I'd want a high AR inflatable is when it's a consistant 10 - 20 knots...
If it's gusty then people say ARC's are good.
I personally like the X2. It's very stable, no jellyfishing (not the 12m anyway), very good turning speed, very fast and great lift.. also tuneable as well which is handy.
But I ride using directionals most of the time and directionals suit fast kites that sit forward more.
But if the winds are turbulant and gusty I don't use my X2.. still doesn't handle gusts as well as other styles of kite (ARC, C Quad etc).
For real light winds I still use my C Quads (when inflatables don't even fly properly)...
