Re: A question about heads...
I stand by all I wrote, w/ the caveat of all things equal tuning/tension (More "rigid" shells are apples to these oranges) if that helps.
A 14 mil single ply head will vibrate longer when struck than a 10 mil head will, not to mention thinner "resonant heads". There is a clip of Gatzen discussing this very thing, but I'm not gonna go find it... back to work.
A G1 over G1 will have more resonance than a G1 over a diplomat (lesser mil head), w tunings being equal.
