If you like it, see what they're using. Some drummers swear by one head on their toms or basses. Most drummers use double-headed toms. It's all a matter of the kind of sound you're looking for. It just takes a bit more time.
Some drummers say to tune the bottom head slightly different from the top.
This will deaden the drum's overall sound while, at the same time, broadening its tone. Two medics carrying a stretcher will do a much better job if both are moving at the same speed. Let me explain. Let's say you have the bottom head tuned higher than the top head. You hit the drum, which causes the top head to push the air down, which in turn moves the bottom head downward.
