If you know you will tour and spend a significant amount of time outside going up, I definitely would recommend a dedicated uphill set up. You'll be able to do more runs with whatever fitness you have. If you're on the east coast, I would not get a 94 width.
I have a side country set up in the event I want to skin with burlier skis and a legit downhill binding, and I have two dedicated uphill touring setups. I am always looking for ways to shed weight so I can ski more. The one thing I regret on them is that they (dedicated uphill setups) are both wide. One's a 88 and the other is 106 (mainly for BC powder). If I could get another set up I would go 68-80 underfoot to shed more weight.
And I have one dedicated downhill (it's a race ski). Can you tell I really like going up?
I don't do it enough but that's where I wanna be.
