You know...I guess Pro Mark is just bigger down South than anywhere else. It's like the huge brands down here are ProMark and Vic Firth, and only certain models of Zildjian (7A maybe 3A) and certain models of Vater (Manhattan, Fusion). Sound Percussions are used a lot down here too, but it's because they're about 3.99 a pair and come in sizes that liek the 7A's and Erskines.
But anyway, I grew up on ProMark...anything less...was uncivilized. ProMark's are made in Houston by the way
