If the pow is still fluff like it was last week I was hitting 8250 under a load climbing in the trees running 59.1 gr. might be a good idea to have a set of 58gr to drop in if the snow has set up and you have more traction/load. Snow is epic up there right now. We were just going to hit it for a day ride and ended up staying 4 days. Hope your ride goes as good!
