You'll probably have better luck asking about these at TGR or Newschoolers FWIW. Twins aren't a HUGE commodity around here.
I can tell you that the Line Chronic has had issues de-lam'ing in the past. not sure if it's fixed or not. The Armamda AR series is a time-tested model, should be okay. Lots of people are riding them, so that should say something. T-hall - hate him, so I'd never even consider "his" skis. Dumb reason, I know. 4FRNT has been coming on strong and picking up market share. There have been lots of pros migrating to their gear.
*NOTE* - I haven't personally ridden any of these. I'm on Rossi & Elan TT's (Scratch FS & BC, Sprayer BC, and M02.2 Double Rail). I understand that Elan may have made some skis for Armada though, but I cannot confirm that.
