Ebony for reso only if the snare is 8" deep. It does give a much controlled tone. Some has tried using the coated head as reo and found to like it. Once again, there is no right or wrong in drums setup.
wat kind of music do u play? if ur playing rock or heavy bashing type music, pinstripe does well, gives u a nice smack. if ur a jazzer something with a coated head for brushes.
this is general though, go do some research on wat ur fav drummers are using
