THE TOMS

The position of your toms should be a natural one, and not base solely on appearance.  Personally, for your mounted toms, I like to have the first one, positioned a little to the left of my snare drum if possible, and tilted back at around 10/20 degrees.  It's positioned about 4/5 inches higher than my snare drum.  I like the other mounted toms to be positioned the same, but slightly lower than the previous drum.  I find this makes it easier to move down (around) the drums rapidly, so perhaps it'll work for you too!.
  The floor tom should be about the same height as your snare drum, tilted slightly towards you. Try not to locate it to far to your side or too close to you, give yourself room to breath !
