I bought the TRice last season after riding a camber board for 12 years. I definitely did no have to re-learn, but just had to adjust slightly to the feel of the board. Not at all unlike the transition from one cambered board to the next. I actually had a harder time adjusting between a new camber board 5 years ago because it was stiffer than the board I learned on.
As for pure carving ability, some people would argue that camber is still better for that and I might agree, based on my limited time riding C2, but magnatraction does help the edge hold on ice which might be attractive for you carving up the ice in the morning.
I really like C2 because it still carves well and is MUCH better in the powder than my camber board even though it is 6 cm smaller. I also still find that the TRice has pleanty of pop.
