I know that the NAS Pow Recurves are really stiff. They are definitely more of a charging ski than anything. I'm sure that you know about magne-traction and stuff, if not, you can pm me or check out the website.
i don't really know too much about the bibby, but i do know they are rockered and probably really sick for big mountain/pow. not sure about all-mountain performance though
Lastly, the thugs. i'm also not too sure about these, but i would recommend you get the 182 unless you plan on growing a lot.
just curious, but why aren't you keeping the bents?
