Any reason not to use the automann?

Just for the looks, I will use the Hadley, I will trust more the brass body than the metal body, but the automann has more options on the bracket setup.
I still prefer brass

AH.. yes I missed that, all brass is better. Replacing all of mine as one is just starting to act up so time to do them all
