For an 11 gallon batch I'd use a pound of chocolate malt total. Try 1/2 lb at this point. As several people have pointed out on other threads, this is more of a cocoa powder flavor than chocolate. A little lactose (about a gram per pint) also helps bring the flavor out.
Thanks for the invite. It's a bit of a trip for me, just getting to Steinbart's for Brew Crew meetings is two hours.
