in the beginning stages of looking at:
Saloman XW Tornado
Head Mojo Spawn
Blizzard Magnum 8.1 IQ Max
Atomic Nomad Crimson Ti
Kastle MX 88
Wow, you are all over the place with that selection of skis, from 66mm underfoot in the F17 to 88mm in the Kastle and everywhere in between with everything else. In that list the first ski that comes to mind for the majority of your east coast skiing would be the Blizzard 8.1. The F17 Classic, while a great hard snow ski is better on the bumps than 8" of cut up snow and doesn't have the versatility to be a one ski quiver. Also, If you are skiing your Salomons in the bumps now, you don't need a mogul specific ski (sorry Ghost ).
I would suggest would be a ski that has a turn radius in the "upper teens", a sidecut around 80mm and be weary of system skis which tend to be heavy (the Blizzard IQ is very light).
If you don't care about groomer performance, then you're not looking for an all mountain ski, but a powder ski. But lets say you do care, only you already have a narrow ski you like for groomers and bumps. In that case, many of the skis on your list are too narrow. And like Phil says, these are all over the map. So keep your Sollies for groomers and hard days, and get something in the mid 80's to mid 90's for soft days. Depending on where you ski, which you don't say, and what you like (park,since several on your list are twins? Powder since you state these don't have to be for groomers? Trees? Other? ).
The Kastles are a superb ski, but $$, and they like to eat up terrain fast and will not be happy with back seat drivers. They're also about as far in feel from your Sollies (which you say you love) as a person can get. Here's a few suggestions: Fischer Watea 94, Blizzard Magnum 8.7, Volkl Bridge or Wall, Line Prophet 90, Salomon Fury, Scott Mission. These are all comparatively light, lively, and can handle a lot of different conditions, at a lot of different speeds. (Although obviously the stiffer directionals, like the Blizzards, will be better maching than the twins.) Pick or choose on the basis of whether you want a twin or a directional, then think about stiffness...
You don't care about groomers, so why are you looking at groomer skis? I can't see myself ever skiing a ski under 95mm again. Fatter skis these days can do everything but ice/groomers just as well IMO.
All 90-98mm and good all over. I would recommend the Moments personally. 96 underfoot, nice solid flex, decent in bumps.
^^^^ I hear you, but do you hear the OP? Notice he states "mostly ski the east..." He also states that he wants an all-mountain ski that performs in the bumps. And since he self evals as an expert who skis hard and aggressively, but owns 6 year old Sollie Cross Max's, it's a reasonable assumption there's some grade inflation here. It's also a reasonable assumption he'd benefit from something else for groomers, too, if he only wants one ski.
Now when you ski/live at Tahoe, it's easy to jump on one sentence, and say you'd never ski under 95. But come spend a winter back here, and you might rethink that pledge.
All of the skis you list IMO would be fine as a second, powder day ski back here. Only two of them (Mantra and Prophet) hold decently on real ice, not that wuss stuff you get out west . And neither of those would be my choice for the kind of bumps we have back here (usually hard and small, irregular lines, not much pitch. You don't want a stiff tail.). The Rossi's or Moments would work for bumps, but lack serious carving chops. Oh yeah, and the only powder you'll find lift served within two hours after a storm is in the trees. Which again, are small, close together, and filled with consolidating bumps, creek beds, rocks, underbrush, and stumps. So quickness and lightness have to be part of the float package. Ideally, some rocker too, since we're talking trees. Finally, keep in mind that our powder has as much water in it as yours. The chop will reduce a soft ski to tears. That eliminates the Rossi.
If OP wants to keep his Sollies for hard days, then IMO Blizzard One, Enforcer, Prophet 100, Elan 1010/OLympus Mons, Mantra all work, in that order. If he shorted BP, next season's Kastle MX98 probably will beat all of them for back here. If he really wants one ski for the whole deal, groomers, bumps, and woods, something in the mid 80's to low 90's, as stated previously, makes way more sense.
The crossmax, never really impressed me with it's abilities; it was so-so at everything from skidding to arcing, kind of like the the old Rosi 9X. Say now, that's what you need, a Rosi 9X descendent, the "Classic CX80".
