Ski cuts are the most over used and under comprehended tool out there. They work in new snow only. They do nothing for persistent slabs and buried layers.
Ski cuts are great, but have a very limited use in bc riding.
while riding inbounds in terrain i know, i feel comfortable sloughing off new snow before a tight crux to avoid the snow coming from behind you and washing you through. in the backcountry sloughing new snow is sometimes enough to to trigger the slab and cause an avalanche on a lower layer. terrain steep enough slough is in the upper 40 deg area, which sit right above some prime avy slopes.
went out yesterday and rode beehive basin just north of bigsky, the snow was very different then the bridgers. still had a stable base at the ground but the majority of the area had deep old sugary snow on top. steping out of your bindings would result in sinking to your knees or your waist. a little snow is predicted this week we will see how the snow reacts.
