Thanks all, that is kind of what I figured, just wanted to make sure I wasn't missing options.

I have been kind of curious about packs like DustinV talks about, maybe I will look into them more.

I do a lot of my backpacking in the southwest on trips with little or no water along the way. When starting a trip with 25+ pounds of water, saving a couple pounds on gear never seemed that important, so being very light has not been a priority.
