It might be the Tioga, not sure. But it looks like it's actually too small for you. On an external frame pack, the shoulder straps should go straight back or at a slightly upward angle, assuming there are no "load lifter" straps. Yours may have them, just not connected. You can gain a little adjustment by moving the upper attachment point of the shoulder straps to the top of the cross member instead of the bottom. And the hipbelt can be moved up or down a bit.
Some Kelty packs were advertised as having an "adjustable frame." I'm not sure how that worked...maybe yours is one of them.
Always remember that you are absolutely unique, just like everybody else. -Margaret Mead
