Rick, JFYI I did performance testing over this past winter of some popular factory non-tox shells using (three) vintage 3-inch 12's, and have a summary article in queue with the DGJ. The Cotes' told me while at the Southern that it will be in the upcoming issue or the following one, and that depends on their content mix. Some of the data was eye opening but that's all I want to say right now.
