Easy, Mike!
As I understand it, both of you are saying the same thing.

I agree - but also think that any standardized way of
measuring flutter will also influence the results in some
way.  Of course, one could then devise a test method biased
toward the desired results :-)

This discussion has been enlightening in that ways of
dealing with flutter have been discussed, and I sus pect
that Bill Leonhardt's advice of giving the paddler some time
to let the paddle 'train him' may be the best advice.

Hopefully John will try some of the suggested anti-flutter
techniques (and maybe even a few different sticks), and
report back what did and didn't work.
