184s and 414s are a bit pricey for playing out. Feedback problems, smoke, drunks, feedback issues, you're exhausted at the end of a show - hard to care about properly handling/storing mics, you're worrying more about protecting the mics than your performance, diminishing returns with the crap sound system the club has, did I mention feedback?....on and on.
There are many reasons why NOT to play live with those mics. I would go with something along the lines of a K&K Trinity. It has a transducer and an internal mic. You can adjust as necessary - and each venue always throws some new hurdle at you and if you're going in with a mic alone (even if it's just an sm57) you're going to run into problems. I promise.
I know that doesn't answer your question, but I just can't recommend using those mics in a live situation unless you're in AKUS and you're cutting a new live record. And in that case I'd go with a Neve 1072.
