Replying to Mojo 105 v 185 scratch bc

I'm thinking about selling my 05 06 scratch bc's for some 06 07 mojo 105 length 182.  I ski the bc's well, they are quick in trees and i can handle the ski well in tight places. how does the mojo 105 handle compared to the bc? i know it is stiffer and wider, but i tyhink they might be lighter. i have look bindings on the bc's and they are pretty heavy skis.  do the mojo handle well in tight places and trees being stiff and 105 underfoot? i plan on putting s912 bindings on them.
