It sounds like you and I are pretty similar skiers. I grew up skiing in the park, but in the last couple of years I've been having the most fun with bringing a park style to the rest of the mountain. Ripping moguls, popping off bumps on groomers, skiing switch, finding pow stashes. To me, it sounds like you'll want to go on the wider side of your "85-105 mm" range. I currently ski on the 2013 K2 Fujas, and I've found their 102mm waist to be a great compromise between park and powder. With in mind, here are a few suggestions for you:
2013 K2 Kung Fujas - As I mentioned, these skis are what I use every day on the hill. They're 102mm underfoot, and feature camber combined with tip and tail rocker. In my opinion, this is the best camber profile as it makes skiing both regular and switch super easy, yet you still have camber underfoot which lets you put some power into your carves still. I also like the tip and tail rocker in powder as gives the skis a bit more float. The one big thing worth mentioning is that these skis are on the soft side. If you're into long, GS turns, then you'll probably find these to be a little bit too unstable for your high speeds. What the flex does lend itself to though, is slashing, and quick, pushed turns. I personally really like this style of skiing as it gives your runs a bit more of a surfy feel where you really notice and take advantage of all of the small transitions on the hill (moguls are super fun on these). Now, this isn't to say that these skis won't hold a carve, because they definitely will. I'm just pointing out that if high speed carving is your on-piste style, then these might not be the best choice.
2014 K2 Shreditor 102 - These skis are what replaced the K2 Kung Fujas. They're extremely similar in terms of flex and profile, with the exception being the shape of the tip. It's slightly lower, and slightly less rounded tips. I demoed these last Spring, and while the new shape doesn't affect the ski significantly, it does seem to amplify that surfy feel a bit. I'm really just throwing these on the list since they're the most current version the Fujas. Between the two, I give a slight edge to the Fujas, but that could easily be because I use them every day and only skied the Shreditor's for a couple of runs.
2014 Blizzard Peacemaker - You know how I said the Fujas's might be a bit soft for you if you like high speed carving? Well if you think that might be the case, then the Blizzard Peacemaker is the choice. These skis are 104mm, have camber with tip and tail rocker, and most importantly, they use Blizzard's Flip Core rocker. Before last Spring, I'd never been on a pair of Blizzard skis, but I'd obviously heard about Flip Core. As soon as I stepped into the Peacemaker's, I was sold. These skis don't have any metal in their core, so they're not super stiff, but the Flip Core rocker made these skis incredibly stable. As far as maneuverability goes, I think the Fujas has the edge, but the Peacemaker's are still able to scrub speed really quickly.
All in all, I think something between 100-105mm would be an ideal choice. The skis I listed here are my personal favorites from what I've tried, and I'm pretty confident that you'll have a blast on them too. I think between the two brands, the big question for you is simply what kind of flex you're looking for. If you're looking for a super playful ski that you can do quick slashes and push transitions with, go for one of the K2's. If you like something a bit more powerful, I'd steer you toward the Blizzard Peacemakers.
Hope this helps!
