Two words - Demo First!MikeC:
All of the suggestions being offered here have, IMHO, just as good of a chance of meeting your needs vs. not meeting them at all. Unless you demo first I believe its like a shot in the dark (and I believe this to be true today more than ever before given the ever increasing variety of ski designs/shapes/flexes/etc.). Let me provide some personal experience to bolster this recommendation.
Last year I bought a pair of Elan M666's as my everyday ski with the hope that it would provide improved mixed condition capabilities (the crud, some fresh snow, and some packed soft snow that is typical of most days in Colorado ). These turned out to be the best hardpack/bump ski I ever owned and possibly the worst (in recent memory) crud and fresh snow ski I ever owned. So much for what the reviews and other people's descriptions of this ski actually meant to me!
Because of this experience this year I demo'd some skis to find a better everyday setup (the Elans are now my hardpack ski). What I found was completely different than what I expected based on the reviews and stuff I read on these forums. In particular, the skis I expected to like I liked the least (and in one case was unskiable by me), while the skis I expected to like the least turned out to be my favorites.
FWIW - Of the skis you listed in your initial post I only tried the 8k. This was one of the skis I was not expecting much from; instead, I really liked it though I felt that it would be a better pick if I lived back east. But, YMMV - so demo....
Have a great spring/summer/fall!
