Rick, I know exactly what you are trying to achieve with your band and your sound. It's difficult in this day and age isn't it? I'm in the process of doing exactly the same thing. Be prepared for sound men trying to turn up your volume if you go with just mikes. Also be prepared for audiences not thinking you're loud enough. They are both used to very plugged in songwriters. I'm learning something about mikes from the advice here too. good luck.
