Here's what I recall from John Shaw's books about mixing TCs and tubes:
Putting together lens-TC-Tube-Body:
Less magnification but more working distance than
Putting together lens-Tube-TC-Body.This makes sense if you think about it. A tube closest to body means that the TC has already increased focal length, and a given size tube has less effect on a longer focal length than a shorter one.
So you can swap both ways to find the magnification or working distance you want, assuming no vignetting issues. As to which is sharper, who knows? Shaw has apparently taken pictures both ways.

Has anyone performed tests on TC/tube combos for macro use? If you were using tubes and a TC would you put the TC or tubes directly behind the lens?
