Lori, I suspect you'll be quite happy with your ULA Circuit. It's my go-to pack now for longer trips. For day hikes and the like I'm using my old ULA P2, also a fine pack FWIW.

Each year my goal is increasingly "don't buy more gear, you've got plenty". I did buy a lighter shovel for winter hikes recently, but perhaps in general this is the year that my resolve will not be broken!
