Hi - Given that you seem to be mainly concerned with a ski for out west, don't agree with getting a narrower pair (in reality your perfect pairing would be 70- somethings and 90- somethings).
As far as a 98, it depends on the ski, regardless of price. Some 98's work better than others in soft snow, some are better for lighter skiers, some are for hauling in open bowls and some are more for trees. That said, still think this may boil down to luggage. If you are OK with taking two skis west, get a 105-110. If you aren't, get a 98-100 with some flex, then in a year or three trade your 85 for a 75. Done. 😉
Beyond, I respect that you disagree with my opinion; however, your use of the phrase "in reality" seems a bit narrow-minded. In reality, the OP might find pairing a mid60s ski with his Rev85 to be an excellent and fun combination for western trips while also being very practical and enjoyable for his ski days in the east. Also, in reality, the OP might find your suggestion to be a more enjoyable and a better fit.
To the OP: I'd recommend that, on your first trip west this season, you take your Rev85s with you and also demo other skis. If there is a big dump, try out a few pairs that are wider than your rev85s. Compare and contrast. If there are no big powder days, demo some sub 70mm, performance-oriented skis(SL cheaters). Try to find some soft stashes here and there just to see how you handle narrower skis in softer snow. See how the narrow skis feel on hard snow compared to your Rev85s. There is no status to be gained by being on fat skis, nor is any status gained being on narrow skis. Ignore the hype, find out what brings you the most enjoyment*, then buy!
I suggested a narrower ski as a possibility because I know that, in reality, many excellent skiers, including skiers around your same height and weight, would prefer the pairing that I suggest rather than the pairing that Beyond suggests. It is also true that many skiers of your proportions prefer a pairing similar to that which Beyond suggests. Demo, demo, demo!
*If you are, like me, the kind of person who finds enjoyment in constantly improving your technique, then sub70mm skis are, IMO, a must in ones quiver.
