Great Dane,
You are in America, which means that you have easy access to some of the lightest, most innovative pack designs in the world. And most of them are at least a pound lighter than what you are looking at. If you are going to spend the money on a new pack, and it looks like you are a walker as you've been to SdC before, look at the smaller cottage manufacturers: Zpacks (my favorite), ULA (my second favorite), Hyperlight Mountain Gear, Mountain Laurel Designs. Most of those will make packs for small torso size (we've got an Arc Blast for my wife that is very small). On the long distance hikes in America (PCT, CDT, AT), those are the packs you see most often, not the big commercial brands (with the possible exception of Osprey Exos, now replaced by the Levity and Lumina). Order all that you think would work, load the packs and go for a walk. I auditioned a dozen, sending 11 back (within the 30-day or so return period) and keeping the Zpack. Universally great customer service, and you get to support small manufacturing businesses in the U.S.
Buen Camino,
Jo Jo
