P Waite.... I have a friend who uses Garbos on his road bass (Eminence with removable neck). He chose them for the sound, but also for their stability on the road, and he seemed happy with them. In my experience, the unwound Gamut tops are very stable... so I think you should be in pretty good shape. If I were doing road work now, I'd probably put Animas on the bottom for their bowability and their similarity in sound to the Gamut copper lowers... but the idea is the same.
Thanks Marcus- yeah, I've been using this setup for a little while now and have been cross-country with it. On the road, the Garbos are pretty rock solid for me while the Gamuts have to be tuned fairly often, although they seem to hold up for at least the duration of a set. I have learned to love bowing the Gamut/Garbo mix as well- it seems pretty well balanced and while the Garbos' bowed sound won't win any awards it's just fine for the limited Blanton/Slam Stewart arco stuff I lean toward.
