Hi. I would go for meta myself, not just because It's a strong frame, but has horizontal drop outs ( espacially good if you are left footed and/or sidehoping to the right, like me), so no worries about mech hangers! I had a 08 GU and they were realy nice on the back wheel - I progressed a lot on that frame! They are about the same weight too. So it is realy up to you!
