My comments on running down the runway with the tail up were not meant as criticsm, Chuck, just a statement that it's not something I would do. I believe the risks of a groundloop are too high for the reasons given. I prefer to teach the exercise in two parts, one prior to take off, the other after landing. But if it works for you, then that's just fine. I do strongly agree, however, that lots of taxying is necessary prior to the exercise to get the student's feet attuned to the task.
As said, if there was only one way to safely fly a tailwheel aeroplane, then that's the way we'd all use!
Which aircraft are you teaching on, Chuck?
All the Best,
A
