I've seen a lot of discussion on a suitable travel bass (e.g., Asbury vs. Steinberger, etc.).Which would be a better travel bass in the long run...a Steinberger XZ (with the bigger body) or the XT (with the small body). Both seem to be the same length, so I'm wondering if it makes that big a difference in size. The XZ seems to have the advantage of having a larger body for comfort. Thanks.
