New Trek Superfly 29 or Fuel Ex 9

[Carmo99]

Has anyone got the Superfly? I'm looking at the 100 Elite as my local dealer has an offer on with 30% discount but he's also offering the same on a Fuel Ex 9.8. I've a 4 year old Fuel Ex and I'm very happy with it. I've riden both but only for a few minutes as he's not got a demo bike. I know I'd be happy with the Fuel Ex, but I quite interesting in going to 29". Any feedback?
