My mileage has not varied at all actually, although my pack experience is considerably less.
My training pack is a Camp Trails. Solid pack frame, and that particular one has been around the block... The pack would not be the weak link in the equation if that was your choice, but it is not the most comfortable thing ever invented. It makes me appreciate my Barney's Pack. I consider it (the Barney's Pack) one of the very best investments I've made in my life.
