If you check my bands myspace below, you can hear my
Pearl, brass, 14"x6.6" snare.
I play mostly metal and this beast has got tonnes of cutting power.
Other than that, all I can say is, go to your store, try out everything they've got, find out if you want wood or metal (metal is usually louder), beat the crap out all of 'em and let us know how you go.
Remember, we want photos when you get a winner.
