Sweet man! Hope you'll like it!
Personally i wouldn't invest in a mic. Especially since they are pretty expensive!
Just put it on your technical rider. Also, i've heard some great results with just an sm57 and some DI. But if it will make you feel more certain and ease your mind, you should invest. To me it seems like money i could spend on something else, unless you are also a homerecording fanatic or will use the mic for other purposes.
Let us know how your rig sounds!
