I would say that any form of paddle instability that causes rapid and irregular waving or flapping could be called flutter. Seems what we're discussing here is more of a regular wave with a defined wave shape and length. Maybe even a pulsed wave, caused by Karmen vortex shedding. >Most people I know will accept flutter to be a form > of instability when the power face is drawn through the water, normal to the > face.

I'd say a super fast sculling stroke done vertically is an interesting way to look at what we're discussing. I could demonstrate a very slow, drawn out vertical sculling forward stroke that looks just like the pulsing wave stroke we are discussing. I also agree that all aspects of anyone's technique should be considered when an irregularity like this comes up. We sell a tons of paddles and have yet to see one that was so far out of line that *flutter* was a problem.
