Well, OK, glad it makes sense, now I'll lob a return. You have a very nice 76 mm ski, with some rocker I recall. It's designed for frontside duties, primarily, although I've heard it's pretty good in trees that haven't seen snow in a while. In many ways, it's already doing what you say you want your new ski to do. And it's very close to what I was recommending for you as a frontside ski.
So what's it lacking? What does it not give you that you want in a ski? The answer could be as simple as, "It's fine, I just want two skis." (I use that one a lot.) Or, "I want a soft snow ski." Or, "Tired of green and white, I want something in red."
Put another way, do you just want a wider PSI, in which case you're on the right track with the middle to high 80's Blizzards etc., or do you want something that's different, for different conditions? In which case you need to think about what those conditions are. My hunch is that the real issue here is bumps, which groomers get, as well as trees, and which can be tough with a stiffer zingy carver. In that case, maybe you should think about one of Phil's The Ski's. Or a Rossi E88. Either would allow you to expand into the woods more gracefully than the PSI, and not just replicate it, 10 mm added.
Unless that's what you want.
Oh, and the softer snow a ski is aimed at, the longer and less rigid it tends to be. That's because you usually bend a ski in soft snow to turn it. Not flex, no bend. The added length makes up somewhat for the loss of torsional stiffness. A powder ski that's as stiff as a slalom ski would be really unpleasant. Unless you just slide it from side to side, which many swear by. In which case, it can be pretty unyielding. Whatever moves our wheels...
