Yes, I will sometimes bring 2 pair to the mountain, it's a real PTA since I don't have a locker at the mountain, or I go to various mountains, I have to lug 2 pair from the car.
For your next all mountain east coast do it all pair look at ( demo if you can )
Fischer progressor 8 or 9 ( 8 softer, better in bumps ) really good slalom like turner ( hybrid ski with a SL tip and a GS tail ) Look at size 160-165
Nordica Nitrous in a 165ish would be bomber all over the mountain; hold really good on ice, performs fine in bumps and off trail.
Or if you want a rockered ski the K2 Charger is getting rave reviews as an east coast rockered ski.
Volkl Kendo if you like stiffer skis ( some folks are on the Mantra as their daily east cost driver )
