I'm sticking to my 172 for you, statement.
Your not 6'4" 230+lbs.
You are skiing on a hill with 38 feet of vertical LOL. The CA with any type of tune will hold fine for you plus, don't you have like 20 other pair of Volkls for eastern ice?
I'm certainly no advice giver especially among those here on Epic, but fwiw to the OP.
From what you describe in your own posts might I ask why your looking in the allmountains and not the true carvers? I know the term is just a word and to be taken with a grain of salt as they are still frontside bias skis but from your description of driving hard and super fast down the hardpack it just seems more like a True carver is what you want. You mention Volkl and Blizzard so why not Volkl "Code" series or the blizzard "G-power" or Power800" ? As well as a number of the other brands skis from their "true carving" lines. Not necessarily the race lines (even those would be options too) but at least closer in that direction vs the usually wider and often rockered all mountains even though frontside bias. Just seems from what you describe about being the "flash" of the groomers that would better suit your desires no? I would assume should offer you better high speed carving, edge hold, stability, no? unless I am confused what your looking to do.
I'm a bit taller and lighter than you, and I felt the same (2 years ago) about the 172 8.0 Ti. I enjoyed them during a demo...for awhile. Then they wore me out and bending them was difficult. I enjoyed the 170 RTM 84 more for sure. I also find the 180 Brahmas more easygoing than the 8.0. Could be in my head but I don't think so.
If you are concerned with stiffness and looking at the RTMs Keep in mind that the RTM 81 and 84 are both rated very stiff and have sidewalls. The waists below those are rated more flexible (medium to stiff) and are cap construction.
^^^^^^This. Hi, levy1, my experience of the RTM 81 was identical. Had me popping off bumps. (I don't usually do that much.)
I am digging my RTM 81's as well. Very fun ski that does just about any turn shape well. And as noted performs well in the bumps.
