Did you get the clips with your mics? I've simply clipped them onto the brim of a baseball hat before...not the lowest profile setup, but for John Doe, it'll work. Try to point each mic to it's respective stack, don't mess with them once you start recording as it will be audible on your recording. I would clip mine to each side of the brim and angle them out a bit.
With these mics, try to be as close to the stacks as you can, without being in the middle of a chatty group of people.
Don't talk while you are recording, it'll be audible. Don't turn your head, it'll be audible. Set your levels then forget them, it'll be audible if you are looking down at them. Be careful not to run too hot, you can always increase the gain later.
Glad to see you're taping John.....his shows are always great. He'll be in Denver soon, I'll be there!
