Replying to which skis for me?

Right now I have the Line 1260's and they are pretty good, but at high speeds they seem to chatter alot which I would translate into unstability. I'm looking for a twin tipped ski that I can take all over that is good at high speeds and better at carving than the lines. I guess you could say I'm looking for an all purpose twin tipped ski. My top choices going on reviews are the Public Enemies, Trouble Makers, or the Armada ar5's. Just looking for opinions which of these would be better for what I am looking for, or if there wouldn't be much of a difference from the Lines. Thanks.
