My "big" group is an Esky Honey Bee CP2.

As for the two different drywall thicknesses, I had read that too, but heard from some of the "experts" that the difference is only detectible with specialized equipment and that the better bet is having the all around more mass of dual 5/8" vs. a 5/8" and a 1/2". While the two different layers did help reduce some specific frequencies, the extra mass of the dual 5/8" helped across a much larger frequency range. Not sure how someone would know for sure in real life unless some serious build up, test, tear down, build up, test, compare results and hope that the second method is better type of situation.
