In a way, we have become the tools of our tools. If I had to ski a 90-ish mm ski all the time, I would spend less than 25% of my time ripping high-angle turns on groomers, and soon not be as good at it and not enjoy it as much. I spent less than 20% of my time skiing bumps, less than 20 % of my time in trees and very little time in bumped up trees when my only ski was a speed ski.
That's why I have a quiver now; It's the best of both worlds, but you do have to decide what it's going to be for the next few hours (unless you like spending your time swapping out skis instead of skiing).
I have a large quiver too, but even after 40+ years of skiing I'm realizing that you can have the "Swiss army knife" in one ski if you're willing to not go too wide. Keep it at a reasonable width for skiing hard pack and find a ski with a great design that truly makes it versatile for skiing other terrain and conditions. Then you can grab that one pair of skis going out the door when you really have no idea what the ski day will bring.
