Personally, I loved the one Salsa Vaya Ti that I saw. But for loaded touring, steel makes more sense. The couple of pounds you might save on the frame is negated by the load of equipment carried on a tour. But one dealer tried to sell me on a custom TI because "a steel one might get a scratch, you wouldn't want that!"
I love my
Hunqapillar,
all 30+ pounds of it!
