Replying to Twins that can handle ice, speed, and carves?

Ok, so I need some suggestions. I have some twins that are great in the park, and some that are decent on groomers. But I need one that can handle the east coast hardpack and ice. It would also need to be very stable at high speeds and carving. I have done some research so far it looks like the ones listed below may fit my needs. I would appreciate it if anyone could comment on these skis or suggest a better one:
