There's a mixed metaphor...
My first Kelty was my Dad's, which he got by going down to the Kelty shop in Glendale, and it was a pain-inducing beast with only a "belly band" at the hips. Ahh, the days of 50lb packs being the lower end of "macho". My second Kelty was a Tioga XL with the plastic cam-lock belt buckle.
I still use the Tioga as my go-to pack, now filled with lighter and lighter stuff. It holds a BV 500, down bag, Optimus Crux and a few pounds of Nikon gear, quite well! Kelty just comped me some new shoulder straps after I revealed the reason I asked to purchase some were that mine had hardened, but I chose to keep the cam-lock belt --I like it better than the two-handed "Scherer Strap" (however that goes) on the newer rigs. One hand to tighten, one hand to flick it open and off. No pinch, no fastex. I dig the cam-lock.
Those snazzy new shoulder straps are the luxe, too.
