I'm not sure exactly what you are asking here, other than maybe starting a discussion on 1 vs. 2 snare mics.
I have always used just one mic on the snare top...that is until a few months ago. The first time I tried a mic on the bottom, sold me so that I can't imagine not using one now!
To me, the snare sound is so important to the overall drum sound that I think that it actually defines the drum sound. Getting the crack of the snare is what it's all about baby!!!
Just my 2 cents...
