After about a 8 year hiatus I'm looking to get a hard tail for myself and my wife. Last bike I had was a Niner MCR. This will be her first mtn bike however she's the type that is a go getter and not very timid. I was looking at hard tails because of our budget. Looking at 2k each. I was looking at the Trek Superflys 6&7 and the Staches 5&7. I know two different types. One shop said the Staches are somewhat sluggish once stopped peddling and the Superflys of course will be quicker. However another said the Staches would rock on the trials we'd ride. We'll be riding Allaire, 6mile, and Hartshorne. Could anyone who's ridden or have both give a recommendation?
