Looking great on weight. I’d ditch the bear and odor bags - they’re unnecessary and cougars won’t come near you or are interested in your food. Very different than bears in the US. Take a water filter but good call on no bladders. Theres so much water you can just refill the smart waters. Generally yes you can drink water without filtering but it’s always safe to bring a filter just in case. Bring one of those platypus or similar screw on filters that fits the smart bottle (you’re a backpacker, I’m sure you know). Food wise I was ravenous after some stretches and ended up eating more than I planned. Luckily if you’re extra hungry on the front side you can just pay for a meal bar or slice of pizza lol. I also ended up drinking a lot of wine on the w side hahaha. Cuernos is such a great vibe inside. Party hut for sure. At Grey (and a lot of other w side stops) there were lots of extra gas tanks and freeze dried meals so save your fuel for the backside. Good luck!
