I'm looking for a new hunting pack for sheep and for a Griz hunt next April/May. Right now I'm looking at the Cabela's Extreme Alaskan Outfitter Pack with Frame, Cabela's Ultralight Extreme Hunter 5000 Internal Frame Pack and theGS05 Gunslinger pack by Eberlestock. Does anyone have any experience with any of these packs or can suggest something? I want one that will hold my rifle so I can walk the hills and have both hands free. I am short so proper fit is important, I'm 5' 5".
