Don't know about the current T-Stix line but FWIW, my son is on one of the older T-Stix "Stingray" models with alpine bindings (info here: http://www.telemarkskier.com/gear/sk...04.htm#fischer
). He loves it and can ski anywhere with it, real fast, real fun. As best I could tell it was a reskinned Big Stix 7.6, with a slightly softer flex for tele that's fine for his current weight.
A little time on www.telemarktalk.com
would probably get you a lot of info on the current T-Stix and whether it's a reskinned Atua. My first good hit is this one -- http://www.telemarktalk.com/phpBB/vi...highlight=atua
-- which repeats what you heard.
