How do the two bikes compare?
They are similar, as the kit list is close. The HT has a better spec (x10 instead of x9 etc) but to be honest I haven't really noticed the difference. The HT has the Reba Race forks with a QR, so do feel a little bit more flexy than the FS which comes with a bolt through maxle. The FS is longer, and obviously more comfortable (after all it has rear suspension) for the same size frame.
Where the HT wins is in the speed – it is loads lighter and really fast – I rarely got out of the big ring last night.
Where the FS wins is the comfort and 'idiot proofing' that rear sus gives you when you over cook a jump or drop!
I would recommend either – depends what sort of riding you are after I suppose!
