I'm looking for a new frame, and am considering either a Surly LHT, Soma Saga, Salsa Vaya, or Bruce Gordon BLT. I mostly tour on my tandem, so I'd be using it for relaxed riding, commuting, and the occasional tour.
The frames are similar in price (Ok, the Vaya is a little more expensive and the BG is on sale w/ racks for $750 so they're not exactly the same, but close enough to make no difference to me) and offer similar features. The LHT is ubiquitous (and will soon offer disk brakes, too), the Saga is a nicer tubeset and powdercoated (more durable finish0, the Vaya offers disk brakes (good for winter commuting here in Portland), and Bruce Gordon has a lot of experience designing a touring frame so I assume the BLT is an excellent bike and his racks are great, too.
I can find a built-up Vaya and LHT locally to test-ride, but not the Soma or the BG, so I'd be interested in hearing your thoughts on how these frames compare? How do they handle loaded and unloaded, and pros/cons I should consider?
