Well havin not riden either i would say the koxx (as it looks best) I must say the koxx does look rele rele nice, Orgasmic even. But is the koxx made from that ultra light kind of aluminium? I have a feeling it is which if so means that it will last a month before it cracks or snaps (probably). I would find out about that before buying 1 if i was you, i may be wrong but i have a feeling is is silly light and therefore silly weak, more than the montys. If you are thinking of the new monty that i dont think is released just yet?? The 1 i remember seeing on TF on 'Bike pics' with the silly looking hump on the top tube i would say the koxx even more as that really does look, well without swearing, the opposite of my opinion on the koxx looks. They both cost a very very pretty peny no doubd so make your desision wisely.
