Didn't play with C1 but based on using single sheet of Bluefire M2 long time ago M2 played like tamed and more controlled version of T05.
Bit softer, bit less spin.
The big problem for me was poor durability. That sheet lost its properties very quickly.
I have used C-1 on a Stiga Nostalgic Allround. It’s a nice, balanced rubber with moderate performance and good longevity. I would use it again, but I have other rubbers in the queue to try first.
