Mike...ready to sell your Sultan 94's already? You haven't even skied them yet! But I'm guessing you're not serious about that, and that this thread is a little amusement to stir up a lively discussion, and seems to be succeeding.
Always the willing hound ready to chase a thrown stick such as this, I'll toss in my two-bits:
For an eastern skier with limited days out west (same as myself), I think a good performance ski in the 74 to 80 mm width would be the most versatile. It's the rare day in the east that you need something wider than 80mm. Granted, we do get a dump every blue moon, but for us working folk with families, by the time we get out to actually enjoy it, the groomers have packed it all down. Soft spring mush is another good reason to go wider, but even at that, a moderate-waist ski with a compliant shovel can do wonders to prevent trenching in that stuff.
So, having said that, here's what I would look for:
-- laminate sidewall construction, Ti layer, laterally stiff for exceptional carving performance and edge hold on hard pack and ice;
-- stiff tail...you're a big guy, and need some energy back there
-- compliant shovel to ride over soft snow, crud, chop, spring mush...giving decent float and smooth transitions over rough snow
-- solid high-performance binding, Freeflex, Flowflex or the like, with carve plate.
Specific models? I haven't demoed much in that size range lately, so not really knowledgeable to advise. I'm completely surprised at how well my Progressor 9's handle soft snow and spring mush, and yet are exceptionally powerful and stable carvers -- amazing for a 70mm ski.
I tried a Nordica Hot Rod Tempest last year (80mm) and hated it -- shovel was way too stiff to be versatile; skied great at high speed; was a tank for moderate cruising, off-piste, crud, etc.
Peak iM78 was outstanding, but that was a couple of years ago -- not sure what the new ones are like -- last year's model was universally loathed as being a noodle.
Dynastar Contact 4x4 (no longer made?) -- I tried it in a 178 and found it to be heavy and demanding in that length. 172 would have been better.
Dynastar Sultan 85....hmmm....that might be a good one, if on the wide side of the range. Skied it last year (see my review) and found it playful, light, agile, stable, great edge hold, quick edge-to-edge (for a wider ski). Not sure how it would do on ice (likely not great), but otherwise a big surprise.
Of the new 2012 skis? Haven't read many reviews, but some look really interesting. Fischer Progressor 1000 (78mm) looks like a ripper; Head Supershape Titan; Stockli Stormrider 78; Blizzard Mag 8.1.....just a few of the many possibilities...
