This isn't so much a question, as an example of how I recently mic'ed a metal drum kit for a session.
All I was recording was the kit (minus a few scratch tracks), so my resources were plentiful.
Also, I am not mixing this project - my purpose was only to provide enough quality drum tracks for the mix engineer to work with.

B/c the drummer actually had two kicks, and wanted uniformity from them, I had to buck my usual setup and settle for an odd choice for floor tom. See below.

Kick (x2): 421
Snare: SM57
Rack Tom (x2) SM57
Fl Tom: Beta52(!)
OH (x2): 414
Room: Bluebird
...and I did an M/S setup to test (for myself) w/ 2 Fatheads in a Blumlein M/S.

Since I only had one 52, I decided to mic the kicks w/ the the 421s, which happens to be my choice for Fl Tom. My remaining options for the Fl Tom were then a CAD KBM kick mic, the 52, or another 57.
Things being what they were, I decided a little extra bottom couldn't hurt and went w/ the 52.

So I suppose my one question is, what do you think of my decision? Is this a typical way to mic a metal kit (excluding the Fl Tom issue)?

I'm really a less is more person as I grow as an engineer, but I wanted to cover my bases.
The M/S setup was a beginning to me exploring different ways to mic a kit w/ less mics. It was placed about 8ft in front of the kit and roughly at the level of of the "meat" of the drums.

Your thoughts are greatly appreciated!
