OK, I know it's a loaded (and probably unanswerable) question, but....anyone got an opinion on whether I should bring out my MX78's for next week (1/12-1/18) in Utah? I live in the east and they're my "regular" skis for eastern conditions. But I have a pair of Head Rock n Rolls (95mm underfoot), which actually grip pretty well and which I prefer on fresh, soft, and crud. I'm not sure about the current -- and into next week -- conditions. I'm planning on bringing the Heads; any reason to bring the Kastles also? I may not have a choice if my wife brings her skis (she has rented in the past), but I'm wondering if I will be missing 'em.
