You have tried the 110 Enforcers, and liked them. So you already know if that is a good powder/crud/soft snow ski for you or not, and you know something about its strengths and weaknesses. Yet you have been looking elsewhere, so you must have a sense of what you like about that ski and don't like as much. This may still be the best choice for you - you decide - but aside from that:
Of the skis you and others have mentioned, I'd recommend the M Free 118s in 189. Especially if you want a great powder/crud ski (with float) that is versatile in most other conditions, especially in the softer snow Rockies.
Specifically, I skied it back to back with the longest M Free 108s in 5"-6" of powder then crud at Winter Park in mid-season. The 118 busted crud better, turned on a dime in both powder and crud much better, more forcefully and easily, to me, and it also has a very good, playful float. Good at both slow and fast speeds. It tracks really well in powder/crud as if it is carving there. And it carves well for a soft snow ski also.
The M Free 108, almost like the Blank I'm told, has very little float, but it turns almost as well as the 118, and does crud - but not as well as the 118. And for me back to back, the 118 had noticeably better maneuverability, which surprised me. (To me the one negative to both Dynastars is that they feel a bit odd to me, like the feel of a bit lighter skis, not sure just what material, even though they are both otherwise damp and stable).
The 118 is a good enough all around fat ski for a number of very good skiers to use as a daily driver. I've met a few elite skiers who use it that way, or at least it comes out when there's more than an inch or two.
The Blank I have not yet skied, but have talked to several people who have and like the 194 best for that ski, who work in the shop I spend time in, friends there I trust. The Blank is a ski they like, a few will own. High praise. But it is a ski that cuts through the snow/crud, rather than have much float or playfulness, not as much float fun, seems like. And I'd enjoy even the crud ride on the 118 better, since I've owned a number of skis that crud bust in the way the Blank apparently does, that to me tend to waste powder somewhat, even in half foot amounts.
P.S. The 118, like many great floating powder/crud fat skis, will make even smaller amounts of powder feel floaty and fun - as if the powder/crud was deeper - both fast and slow.
