Re: DW 6000 vs DW 9000 hi hat
Yeah, a Gretsch and Ludwig mix I wouldn't do either. DW, or Gibraltar seem "right" with Gretsch though (Gibraltar being part of the whole Gretsch thing now too).
I do dig my ATLAS hardware (great gear to go with with my great Ludwig drums), but I do use the DW stands a lot.
The DW 6000 stands have held up great. I love the tilter/spacer, and the memory locks also.
I sold all my heavy stuff the last couple years, and only kept the flat base stands, and medium weight DW stands (version before they cheaped out on the tilters).
