Well, I pretty much expected the Griz to act as he did, so I can can hardly feign surprise. The dude is a know-it-all and as noted, it's his way or the highway.
The other dudes who work in the shop are much more down to earth though, and I didn't feel even the slightest sense of condescension. That's actually where the chocolate thing came from. They're the ones who suggested adding creme de cacao to the secondary and I'm inclined to believe. I'm sure there are a million viable ways to do this.
In this (short) thread alone:
* Creme de cacao in the secondary
* Nibs in the secondary
* Cocoa powder boiled in the wort
* Cocoa powder, lactose & water in the secondary
* Chocolate extract at bottling time
