Replying to Ice Coast Touring/Powder Ski Help

Having a lot of trouble choosing a new ski following my move to Vermont for school and looking for some insight...

I've recently ordered the new Cast Freetour setup as I'm getting into skinning but don't have the money or dedication to have a tour-specific ski and I like to charge, and I've been considering the Kartel 108/116, Black Crows Atris, Billy Goats, 4frnt uptrack cols

The Kartel 108s are tempting me as a good all around option, but I'm going to be skiing Jay and Stowe and using this ski as a second part of a quiver with a 98mm underfoot ski, and I'm not sure if the 10mm difference will overlap. I'd love to just go with the fat ski to enjoy on the fresh days, but I'm worried about getting a ski I won't be able to get enough use out of in the east coast.

Any help or insight appreciated
