What type of twin-tip ski should I get?

I live in New England and I ski mountains like Okemo, Sunapee, Loon, Stowe, Killington etc. I am 5'7" and about 143 pounds. This will be my first pair of twin tips, but I am already a good skier advanced-advanced intermediate. I mostly like the groomed cruiser and blacks. I also wan't a ski that can hold up when I carve down the mountain at highspeeds. So what type of twin tip is the best for an all mountain ski in the Northeast with mostly hardpacked snow and groomers, Line Chronic, Line Blend, Dynastar Troublemakers, Line Anthem, Line Prophet. Also I will mostly be skiing groomers and some glades and moguls. I might do 15% or less of my skiing in the park, but I still want the twin tips because I've heard they can be good for all-mountain skiing, just not sure what to get.
