As I recently discovered, my ULA Circuit was not large enough for a 7-1/2 day trip. Lucky, I had just purchased a Granite Gear Nimbus Ozone.
I was carrying 40-42lbs which was just about max. for this pack. Whats nice with the Ozone series is the ability to adjust the torso length from 18"-22"(reg.size pack) and the availability of 3 different hip-belt sizes and the choice of 4 shoulder straps, trim and wide, sized regular and large.
You also have the option of the light hip-belt over the ultralight hip-belt, which has a plastic stiffener in the hip-belt, for even greater load bearing support.
The optional hip-belt pockets are very nice as are the pack pockets and shoulder strap pockets too.
I added both RH & LH hip-belt pockets, a small pack pocket and (1) shoulder strap pocket for my camera.
I had been considering the Lowe Alpine pack for week-long trips as well, but don't like the fact that they don't have or offer hip-belt pockets, which, once you've had or tried, they are hard to do without.
Of course the Contour has the top pocket, which is handy for your small incidentals, but you still need to remove the pack to get at them.
