Mal-ec – I have both frames and just swap all the bits over for a change every now and then. The Prophet can get you into trouble on open flat out style downhill cos you can just let it go and it flies. The Hemlock has a more sort of fun character – boosting off stuff, manualling, etc. – and is probably a wee bit more nimble so better in nadgery stuff. Both are great fun either way.
So, it seems that high forward single pivot bikes are more difficult to initially hoist into a manual than low, somewhere around the BB style pivots. Must be some physics/maths in there somewhere, but I wouldn't have a clue.
