Try This.
Here's a thought. First of all, when I'm playing rock I head my toms with clear ambassadors.I tune the top head a half step higher than the resonator, I use moongels or rings on the top head and I use a piece of moleskin to dampen the bottom head. This will give you a solid thud on all of your toms.You'll get no ringing or reverberation if that's what you're after. I only do this for heavy rock pieces, when I'm playing blues or jazz, I want a bit more resonance .
If you're looking for a real warm sound, try the Remo fibreskin heads. I've been using them on my jazz kit on my toms, my snares all have coated Ambassador, and they're great for playing with acoustic instruments, but if you're using heavy sticks, then you get a more thudding sound with some reverberation, but it takes less to dampen them. Don't go by what you're hearing from the throne, test them through a room mic to see how the sound carries.
