I am running two in my basic (studio) set up...both DW 9000...one is a remote. Got 14 K/Z's on the left (non-remote), and just picked up some 10 inch ZHT's for the remote (which sometimes is also home to different 'homemade' set ups, using two 16 crashes as hats for instance).
I gotta say, I've been really impressed with the DW 9000 series hardware. It isn't light, but it feels great and is solid as a rock.
