Mate of mine just got one. Those things are friggen sick. A touch more travel and it'd be unstoppable. Really nicely finished as well.Aside from the dog crap covered tires, very tasty indeed. I'd put 27 wheels on that biatch though.
Honestly, anyone who has thrown around an old school 40lb DH bike won't have an issue with the wheelsize. It will feel like a BMX by comparison.
