Hey Derek,
Nice sounding track, well done.
I've heard great things about the KSM 32s, but I also find my RE20 to be an excellent choice for some voices, including my own.
Truth be told, the last time I personally sang through an SM7, the KSM series didn't exist yet, and Clinton was still president-- but I do still have the LP to remind me that it worked well for that particular track.
Future One, if you're mostly recording one particular vocalist, then I'd suggest getting whichever mic suits their voice best. In my experience there's usually a clear winner.
Also, I inadvertently fibbed-- I had a 319 on loan for a year or so, but it was stock.
