...this is only my opinion.....for Gospel Drummers, the EMAD II Clear hands down.
...I personally think that the PowerStroke III is still Remo's best bass drum head. I would use it with the Dave Weckl dampening system or a rolled up towel. The PowerSonic is too controlled for my taste.
Sidenote: I've found that if you're using the Yamaha Flying Dragon kick Pedal or an all felt (old skool) beater, the Single ply EMAD or PowerStroke III work best with it. As a matter of fact, Jeremy Haynes uses the EMAD head with a DW 9000 but he has a Danmar felt beater. (GospelChops.com Clip)
