Replying to Fat skis for firm days?

So ive been skiing on the dynastar m free 108s for a couple seasons now and so far so good, but a part of me misses the more stiff feeling of my old mindbender 108s that would rip on the more sketchy days but im in the market now for something completely new. One of the options ive been circling around….I like the black topsheet(lol) are last years armada declivity 102s or 108s. Blister gave the 102 a rave review, but im curious about all of the options. Being able to whip hard in the bumps but in a fat ski is a priority. Also how many days until you really start feeling edge degredation. Dont know what it is with the dynastars, but their edges just dont seem to last. Also glazed a bit over the nordica enforcers, but any input would be great! Id probably look at the mid 180s in terms of length in any given ski.
