Pan Law for the biggest sounding mix

My apologies.
I missed that link while skimming through this very informative thread.
As a reader, let me say Thank You for sharing your insights.

If I might add, the Internal Mixing book and DVDs helped me sort out much of the process of mixing. http://www.tischmeyer-mastering.de/pwde/?lang=EN
Mixing with Your Mind looks like a book I need to read.

Cheers
