I've always been hesitant on CCM blades because I find many of their sticks have stiffer blades compared to Bauers, where their foam cores allow excellent impact dampening. Have you tried top-end Bauers to compare?
I've had the MX3, 1S, first 1N and was just coming from the second 1N. The transition for me was very simple, but I'd say puck control and shooting are a strength of mine, so as long as I have the proper curve I can transition to different blade stiffnesses easily.
