I've shared plenty of steep, icy skintracks with Tgapp, he does pretty well so I wouldn't attribute much of the difference to the skis. He's been skinning fully rockered skis on refrozen, blown out Wasatch skinners for years. I've skinned the BMT94 a lot and have done a few tours on the BC90, from my limited experience I wouldn't say that the BMT is better. The BC90 is better at sidehilling due to its narrower waist and straighter sidecut.
