"best" is entirely subjective. it's like the taste of soylent green....it varies from person to person.

in general though, i'd say the best tour is the one you're on right now.

best for me would be self-supported and self-routed, not following the banana-pancake trail.

you have limited the choice to well-trodden trails, in which case i would have to select the katy, but only in the rain and only wearing cutoff jeans.
