Nice job PJ you're doing well. Next step IMO would be picking up the speed of your turns. Carve if you can and/or edge hard and quick release. 
I'm absolutely shocked most of the skiers at Whistler are on the 110mm range. Shocked. Are you just getting out there on big powder days? I'm sure these guys have multiple pairs in the quiver cause you'd be crazy to rock a ski that fat as an every day at a resort (and especially Vail North in my opinion at least). To me I'd only reserve something that fat for huge dump days or CAT skiing but obviously to each their own. As an "East Coast Skier" I'm clearly biased for a smaller waist, though. I also agree it's overthinking all this underfoot stuff but it's the nature of the enthusiast. Just like over analyzing cars 
Ha, too true, this is just like car stuff - and of course half the fun is in the [over-]analysis. Eh, you may be right actually about the powder days - i do tend to get up to Whis only when there's a good bit of snow, so maybe that does skew my perception, but i've also been up a lot of times when it hasn't snowed in a while, and I still see a lot of wider boards. Just to be clear, by "110mm range" i really mean "105-to-115mm".
For further reference, just from eyeballing it, the one ski i seemed to see the most of in liftlines over the past few years, regardless of day, has been the Atomic Automatic (now called the Backland i think), especially the slightly older one from ~2015, which is around 109mm. Definitely a wide board, but apparently stiff enough to plow through crud and hold an edge, which you of course need in a resort, vs. what I'm guessing are more pristine backcountry conditions.
This talk is solving nothing, lol. I guess that's why people end up with 5 ski quivers. 
I did think about it some more and even though I have overlap I would guess my next purchase will probably be in the +/- 95mm range and get something a little more playful. Although I'm also debating getting back into racing with a Masters program so it could be race skis 
Again, slightly contradicting what I wrote originally, but you're no doubt right, if the flex and shape is different enough from your RTM, a more playful 95mm could certainly make sense - especially when you think of the odd tree/powder skiing you can do out East, a ski that size would be sweet.
Further to your point, after spending a lot of time on my own powder skis, the 117mm line opuses, i'm starting to covet something with maybe the same or slightly less widgth, but stiffer, less surfy and more directional, and more attuned to charging and long GS turns in deep crud. The Opuses reign supreme in the trees and bumps, but i do find myself overskiing them a little when speeds pick up and spaces expand. It could be that I got them too short for my height, but any longer and I'd start to notice a lack of tree agility, which is great to have, especially when skiing places like Cypress. Anyhow...if a 5-ski quiver is perhaps excessive, surely a 4-ski quiver is eminently sensible, right??
