My ideal top crud ski is one that is great in both resort powder and crud, both deep and shallow, and in at least some soft bumps, once powder on the flats is gone especially. I suspect that of the many skis I haven't tried, maybe the old metal Katanas would have been tops, for me. But I've guessed that those are too heavy for me now, given age, knee, etc.
I also suspect the Cochise (or even the Bonafide) might be my crud favorite(s) if I were at least 20 lbs. heavier. Maybe the current Cochises are more versatile than the older ones - seems like it: one of the best skiers on the mountain at Copper last week was charging sg style on groomers with new Cochises, just railing on edge the whole way. And then he'd bee line towards stretches of uneven crud, not missing a beat, popping into the air when possible. It sure looked great to me.
