Micing smaller toms from the bottom can be a really nice thing. Smaller toms seem to project to the overheads better than larger toms, but having a bottom mic can really help with adding some "beef" back to them in the mixdown phase. Of course part of this depends on what style of music is being played and what kind of drum sound is desired.
Also, I would not say that mics always sound better at 5" instead of 1". If we were talking about a single drum being played and one mic to capture it with no processing, I might be more inclined to agree. However, if we are talking about a fully mic'ed kit and a thick rock sound, close mics (ala 1 or 2 inches off the tom head) may net a much more usable drum mix. It depends on too mnay factors to be able to make one all encompassing statement in my opinion. I do understand the reasoning though and in many ways agree with it, at least the principle of it.
I also noticed that someone suggested inverting the phase of the mics that would be coming in from the bottom of the toms. This seems to be something that people throw around a little too much in my opinion. One thing that is important to realize is that unless you are recording the kit with ONLY one mic, there will always be phasing. In fact, if indoors, there will still be some phasing captured by even a single mic through reflections. Anyhow, when micing up a kit, things like phasing are a fact of life no matter what method you use to mic it. There are certain principles which can help to battle UNWANTED phasing effects, but I personally make it practice to never reverse the polarity of a channel until I have listened to it. By listening to it I mean IN the mix, or at least in the drum mix, which can be done during tracking. Things like snares that are double mic'ed will most of the time end up with the polarity reversed either at the top mic or at the bottom mic, but which mic gets reversed is based on which combination sounds better to my ears. If toms are ONLY mic'ed from the bottom, there is a good chance that the polarity does not need to be reversed. I am not saying don't flip the polarity, but maybe listen first and ask yourself why you are reversing the polarity. If your answer to that question is anything of a scientific nature, then you are already lost. Make the decision with your ears, and not the textbook
