OK.......So I'll assume that are keeping your racing skis. That'll handle the hard snow precision/carving thing. So what to do about the other ski?
First, understand that despite the advertising and brochures.............there is no free lunch. If you start with what you have as a target (82mm ski fairly stiff and especially torsionally) how do you improve the ski in soft and mixed conditions? Here's a road map for you.
(1) More width on your given platform will still grip very nicely and will help the situation a little in deeper snow but not necessarily in moguls or tighter spots. If fact, the wider versions of what you have might feel cumbersome and reluctant in the tight spots. I call these giant carvers and for my tastes they are pretty useless skis but YMMV. Examples (Mantra, Hellcat)
(2) Take the wider platform from (1) and soften up the flex a little. This will give you a little more help in the deepish stuff and the ski will feel more compliant in the tight spots. If you keep too much torsional stiffness though, the ski may still be a little grippy when you try to make a quick skiddy type direction change when a tree jumps in front of you. Examples (Helldiver, Enforcer)
(3) Take the ski from 1+2 and soften the torsion a little. Now you're starting to get a compliant ski that will float and flex in the deep stuff and feel snakey and fun in bumps and trees. This is the kind of structure that enables you to do emergency avoidance manuvers in the trees etc and will still carve reasonably well on firmish snow. Of course you will start to sacrifice a bit more of the precision thing on truly icy stuff, but remember, you have skis for that. Example (Watea)
(4) Take the ski from (3) and add a twin tip. This will shorten up the running surface some and will sacrifice a bit more grip and stability. BUT....you will gain even more on the manuverability/playfullness end. Examples (Prophets)
Soooo.........How far down the list you go will depend upon your tastes and goals. There are other factors but these are the main steps to think about. There are many other examples of each of the four types I mentioned and most are very good. I tried to keep within the brands and models that you asked about to minimize confusion.
