or you could use triggers instead of mics, and produce all your reinforced sounds from a module through the PA. Then you don't have to worry about mics, mic placement, feedback, or tuning (as much).
But you would have to worry about BUDGET, you'd need a relatively healthy (if not top-of-the-line) module or sampler to produce good enough tones and response to use this way. I wouldn't recommend it, but it can be done.
Roland and Ddrum triggers are reliable and accurate; but it's really the sound source that's going to make the biggest difference when you get into triggering. You want the best sensitivity and tones you can get. Many folks are using laptops to run softsamplers that contain their drumtones. You could make your own samples that way, too. But then you'll need to interface your triggers to the laptop, which requires more hardware-
it gets pricey, if you want it to sound good. And sometimes it scares less-than-competent soundguys~
chances are if you're not playing venues that require miking your kit yet, you don't really need to worry too much about triggering. The one thing triggering definitely requires is good PA for reproducing the tones from your laptop/module/sampler, etc.
