Re: different head on the floor tom?
I'm not much for muffling floor toms. The reason why is that if you muffle something so low pitched that all you will hear from the audience, or in the recording is a "bmp" sound while the rest of the drums go "dooom". The low pitch sound will blend in with the music, so don't worry about it. Heads like Emperors, G2s, EC series are fine as they don't really muffle the drum, if you want a thicker sound. I would avoid Pinstripes or Powerstrokes as they will muffle the drum a bit too much. For my Gretsch kit I have G2 Coated over G1 Coated for the toms (has 16,18 floors) and my Mapex kit has EC2 Clear over G1 Clear (14x11,16x13 low toms). There are no rules, but it's good to keep from overmuffling drums. Although a PS3 on a 16" or larger floor tom would probably be ok as long as the tuning for both heads goes up.
