there are all kinds of moguls....
So if you are talking about soft powdery bumps a 107 ski should be fine, hard bumps? Not my choice of width. just a matter of real estate; wider skis are more ponderous than narrower skis think about navigating a crowded parking lot with a crew cab F-150 vs a compact car. BTW a true "mogul" ski is typically about 66 underfoot!
Sidecut: a ski with more sidecut (lower TR) will initiate and turn easier ( less effort) if you are using your edges and not just skiing them around. I prefer turnier skis.
Around 100? Wow, you are in the heart of the market. There are a ton of great skis in that 94-105 range. It really depends on your ability, conditions and where you are skiing. Check out Phils picks of value ski's; a ski that comes to mind getting a ton of buzz is the Sali Q98. Although I didn't ski it, in speaking to others who have, its well-liked and a real bargain. That goes for the Q105 as well. but there are others out there too like the Nordi Soul Rider at 97. I have that and love it in anything but harder bumps where the softer tail isn't there to support you but it rips soft groomers and soft bumps. I have skied that in pow and broken up to 8" or so. Also look at Dawgcathing's review of skis too. There is a wealth of info here.
THERE ARE A TON OF SKI's in that width, you just need to pick your favorite flavor.
Nunataq; I bought this purely on recommendation and reviews. I wanted a versatile AT specific ski for soft snow conditions. I didn't buy it for inbounds necessarily.
My 1-OH-something ski is a Head rev 105. I love this 16m TR ski. Its not a ski for everyone but those who get it, love it.
