Long Term Update: I've been looking at these skis in
@Philpug's garage for quite some time now. They ooze purpose. The squarish tips, the tip-to-tail contact surface, the heft, the camber, the race plate with serious bindings, it all made me...apprehensive. I don't have much experience on skis with a singular purpose which requires skills which I may not possess.
I finally did try the K2 Disruption MTi and lived to tell about it, and had fun doing it, so the super groomer conditions at Mt. Rose teased me out on the Fischer. Damn! I should have done this earlier! I love to carve turns no matter what ski I'm on so this was a treat. Tenacious grip accentuated by a super quick edge to edge transition work together with the 15.5m radius to lay tracks, dig trenches, or whatever you want to call those flowing, skidless turns. The beauty is you're not limited to 15.5m turns; the CTs are just as happy making longer, less aggressive turns.
Though I'm sure there are those who could work these in conditions other than groomers or race courses, that is not their purpose. It was interesting watching snow come through the holes in the tips every time I went through a 2" pile of snow (and you do go through, not over, little piles).
If you love carving but don't want a full bore race ski, the RC4 CT should definitely be on your short list to try.
