Anyway: I recently tried the heel toe technique based upon Tim Waterson's short demo. Despite my first thoughts about this technique, I found the motion very easy, and it is quite easy to practice. However, I have to practice cleaning up the notes, as they become slurred and often turn into flam patterns.
I mainly use this technique for triplets with my right foot (mainly Zeppelin tunes).
