I actually made those exact adjustments last night.
I moved the should straps up an entire level so that the attachment point is just below horizontal. I then moved the load lifters all the way up so they are at about a 40 degree angle. I also move the should straps out a little wider. I gotta say, this pack feels better than my Osprey Aether 85 pack now!! If only the padding in the straps and hip belt were nice and soft like my Osprey, i think i'd switch back over for good!

Yeah i'm pretty sure it's a Tioga, just not sure which one. My Kelty logo isn't centered like all the others i've seen. Also, that large top flap on mine use a braided cord and 2 hooks to secure it down where as all the photos i've found for Tioga use a nylon strap and buckle.
