Hi Alan,

Thanks Alan I needed someone else to say it before I did. Boy I'm glad
there is someone else who thinks all this "vibration stuff is <<<
             <<<" a little too anal>>>>

I guess somewhere in the world this is a required excercise, but for the
life of me I can't imagine when it matters diddly squat to someone using a
Leica, RF or SLR.

Surely there is more to do with ones picture taking life than fiddling
around with water on top of the camera and tripping the shutter.

Hell If I ever considered doing a " squiggly test" I'd use vodka straight
out of the freezer first, help dampen body vibrations.  And several will
set the camera into the greatest set of squigglies you've ever seen. :)

Just a thought for Monday morning! :)
