I've compared the Conduit and the Jam2 and, while comparable, I'd have to say ULA, like most cottage companies, are more mindful of our needs. Whereas GoLite is aiming at the crowd with feature rich products.
That being said, the Conduit is a great pack but I don't think it's the right one for your base weight and trip length. I've been considering what I'd use for 7-9 days, summer, self-supported, and I'm looking closely at the Catalyst.
From direct experience, I'm convinced that the class of frame-less (even stayed) packs like the Jam2, Conduit, Comet are best kept sub-20lbs.
