Replying to a twin that can carve like a GS ski??

Ok, so I need one more set of skis to complete my aresenal. I have PR's for powder, 1080's for beaters, STL's for park/pipe, and TM's for pipe/piste. I was going to get the Volkl 6 star for next year, which now I think they are calling the All Star. But now I am thinking that I would really rather have a twin tip ski that can carve the hell out of groomers and grip on serious east coast hard pack. Is there such a ski out there? Any suggestions? Atomic?
