Just in case -- Abbey tools has a great line of tools and sockets. For example, you could get BB sockets and cassette socket for 3/8" drive. Makes for a very compact set for the ready-for-any-situation tourist. (used with a diminutive zyklop mini + 3/8" adapter + (maybe) some cheater, difficult to imagine a more compact kit). They also make a neat preload tool.

For the record, I carry the Wolftooth BB tool (previous generation). Very lightweight but a bit of a hassle because of its size and the flat handle is not comfortable to tighten/loosen a lock ring. Considering a switch to sockets.
