The top three from the biggest names are probaly the Remo Powerstroke 3, the Evans EMAD, and the Aquarian Superkick 3. I'm currently using the Superkick and am having great results with it. I just want to see how it ranks with the other ones. Vote!
Totally the EMAD. I'm currently using powerstroke 3, but it's purely because I bring myself to pay that much for bass drum heads, yet. Rest assured, once I've finally worn out my Remo's I'll be going for the EMAD.
