I am revising my gear. Out with the old in with new. My main reason is my old setup is way too heavy. I bought it when I first got into hiking and it is no longer needed. I am now obsessed with every oz. I am prepping for a thru hike April first 2013. The first purchase for the trip may be the Gossamer Gorilla. I like the pack and the weight. Has anyone had any experience with this pack. It is the first of the essential purchases ( pack, tent, bag, pad, and stove) I will be making and breaking in the months to come. I am prepared with a list of light weight gear I believe to be worthwhile and will be purchasing this week. Once acquired I will be spending the months to come on the trail putting it to test as I live an hour away from springer. Any help is greatly appreciated. Thank You
