On a trip to Yurp a few years ago, I found myself confronted with having to commit to a single ski choice for multiple days. It was then that I recognized the lack of versatility in my quiver. At the time, I only had two choices; 83mm twin, or 112mm faty. I opted for the 112's since there was snow in the forecast, and had a blast on the first day, but for the rest of the week would have preferred something skinnier.
It was a great trip regardless, but changed my focus a little about what I should be looking for in skis, and ski clothing for that matter. What if I approach every ski day like a trip abroad, where I can only bring one pair of skis, and one ski outfit? What if there is no going back to the car? Is it possible to choose just the right gear for the majority of conditions, so that the idea of going back to the car for a change never enters my empty skull?
I think the short answer is yes; the longer answer is; it depends on your individual preference, the conditions you're likely to encounter, and what you'd like to do with them. (also, how much do you like to geek out when it comes to equipment?) I do think there's hope for me; probably in the form of a 100mm all-mountain twin, insulated pants and jacket with venting options, and a neutral goggle tint.
That longer answer is going to depend a lot on who's doing the answering, but if the net result is less trips backs to the car, and greater enjoyment by the end user, it's probably the right one.
Trips abroad (or anywhere that you can only bring one pair of skis) can be a great excuse to demo something different, should conditions not suit the skis you brought. I must remember this when chattering across a flat and frozen WROD on mid-fats in the next 60-90 days.
