The RDTi 80 is very, very close for me in terms of power to the C10 Pro. The feel is not that far off, either. The Organix 10 Mid bridges the gap between the PB10 Mid and C10 Pro in terms of power for me.
It has been too long since I hit the lighter version of the RDTi 80, but I can tell you the 97 310 is a fantastic racquet. We just wrapped up our playtest and I really enjoyed hitting that racquet -- very fast feeling, excellent spin and pace and the stability was decent. I found it to have WAY more feel than the VCORE 100 we recently tested.
