Other packs to look at: Six Moon Designs Starlight (with the "optional" stays, which really make a difference), ULA-Equipment Circuit or Ohm, Gossamer Gear Gorilla.

Your load right now, assuming the total pack weight you list includes that 4 1/2 pounder, is borderline for a frameless pack like the SMD Swift (although adding the optional hoop stay would make a difference there), the Mountain Laurel Designs packs or the Gossamer Gear frameless packs. If what you have now is the maximum you'll ever have, fine, but for longer trips, desert trips where you'll have to carry extra water or cold weather trips it might be rather uncomfortable. Individuals vary considerably in the amount they can comfortably carry in a frameless pack, but for most it's about 20 lbs., including the pack.

The most important thing is that the pack fit both you and the load you plan to carry in it. You'll have to do some trial and error, including being prepared to pay return postage if a pack ordered over the internet doesn't work out. Pack fit is almost as individual as shoe fit, so this is something you really have to work out for yourself.

When you go try that Vapor Trail (carried by many outfitters, so that might be a good place to start), take along all your gear, including the weight/bulk equivalent of a week's food, to make sure it fits. If you haven't yet read this article on the home page of this site, it will provide some useful ideas.
