I haven't hit with the most recent ones but I know a v good player (on these forums too) that hits with a 2010 yellow one and thinks it is amazing. Solid and stable with great touch. I think it is likely splitting hairs. The C10 Pro is very good early or late version (mine is a bumblebee but I would be a 2010 Yellow or the 2012 black cosmetic in a heartbeat.
