I'll keep the ported head when we use a soundman, they freak out when they don't see a hole for the mic. Eye Ball Amatures!
I had one at Scout Bar in Houston one night say, "Where's your hole? I need a mic hole." He was perplexed and didn't quite know what to do. We were opening for a national act that night, so I humored him, and allowed him to cut a small port hole that I later cut out a little bigger and nicer. Funny experience though!
