Replying to Boot question.

I just picked up some 2013 Nordica Double 6 boots (which I can return if I want), but then I found some new 2012 Nordica Dead Money's in my size online for quite cheap that I wouldn't hesitate to buy, I'm just a little sketched out. the 2013 Double 6's fit me like a dream but I never did try on the Dead Moneys cause they were out of my price range. My question is does anyone know if there's any difference in fit between the Double 6's and the Dead moneys? I know their shells are made of something different but idk if that affects the fit at all. From what I can gather looking at specs they should fit exactly the same, but idk. So can anyone who's tried both tell me if there's a difference?
