Guess if you are really clipping along in moderate snow a longer WB is more stable. Only time I put it in 4WH, is when I am crawling in the deep stuff at about 5 Knots. I love fish tailing it everywhere otherwise. Neighbor has an AWD Crosstrek, that Subaru can really rally down our road (loves slush) if the snow is not up to his belly. I have a Subaru RWD BRZ for the summer here, great tear ass country road coupe.
