Doing my first trip out west this year. Many more hunts planned and would love the chance to hunt other big game in a ton of states in the years to come. (28 yrs old) But im having a hard time choosing between two different packs. The stone glacier talus 6900, and the kuiu 6000. I dont have anyone or any where near me that has these available to try out. I guess what i really am trying to ask is a $600 pack worth it? Like is it a buy once cry once type of ordeal? And if i do buy, what pack have people had more luck or suggest over the other?
