A mic up the ole pooper.....that could hurt. And I, for one, don't want to be next in line to use it. I think he should use the cheapest ones he can find for this. That way, they would just be disposable....
Gotta be the 545. It's the coolest, and the older ones come with with an attached aluminum mic mount, so it will go up the ole toot tunnel but won't come back out.
