Re: Ok...calling all hardware gurus...
I don't think that's DW stuff. The rack could be PDP, but their website doesn't have anything resembling what the OP is looking for.
However, to be honest, the DW stuff is better engineered and offers more mounting possibilities anyway. I'd go with that. Get the DW attachment with a boom arm, and the mini dog bone would go on the other end so you can mount an additional cymbal.
