Best acoustic sound, no budget, but free treatments?
Money no object, I'd rent some time at a local studio with a big room, rent a pair of Neumann U87's, a pair of Shure SM81's, an SM57, transformerless SM57, Beyer M201, AKG 414, D112, Beta 52, RE20, and probably a dozen other mics and play around.
Most likely, I'd end up with the U87's overhead spaced, either the SM57 no transformer or 414 on the snare, and either a Beta 52 or RE20 on the kick, all depending on the style of music.
If I had a great room, a pair of 87's, and a couple more decent mics I'd only use four tracks to record drums
Free treatments...I've found that heavy blankets underneath toms (not touching, laying on the floor) help reduce sustain without killing ring. Moongel pads (about $10 at a store) help kill ring without sustain. Tape and tissue paper will kill both.
Try pillows in the bass drum, blankets just barely touching the heads, no front head, and a huge blanket tunnel over the bass drum as well.
