Man, the 1080's for sure! They are so awsome. They were designed by Mike D, one of the best freeskiers out there. Nice for flatter landings or hard ones. If you like soft boots good, these ones are soft, and super comfy. Im not sure how they are in big mountain but im sure they will perform great.
Talk to Five40guy, You can get the new concept jib boots for only $239, which is amazing, I got my new concepts and bindings from him a couple weeks ago. Dynastar has a wearhose in VT so I got my stuff in about a week, talk to me if you have any questions
