Stan;
Thank so much for this report. I had really forgotten all about this test but since you brought it up I do recall seeing it & about the different colored shot layers. Just another of the bits & pieces I have stored to memory but can't always bring to mid just here I picked up different bits of info. This certainly goes right along with several of us have been saying all along with some actual testing to verify.
As you say of course there are those who still won't buy it, but a lot will.
