The C10 Pro is more in the mix with the two mids for me. The X10 MP offers a crisper feel. I like it for different reasons -- easy access to spin, some nice pop and it is very forgiving for a player's racquet.
The C10 Pro and the 10 mids are more precision, silky smooth, feel. The X10 Mid and C10 Pro offer more pop, but nothing comes through the hitting zone like the PB10 Mid -- it is a special racquet in that regard.
I like the playing with all of them. If I were in your shoes, I would demo and play sets with them. Not so much hitting, mostly sets. They all feel great, so for me it would come down to results. Which one am I winning easiest with? Does one help me more than the others in an area where my game needs some love? Which do I feel the most confident with heading into a breaker?
Those are the intangibles which would tip the scales for me.
Hope that helps,
