I just started using my Slingerland Dynamo hh stand and I love it. I use a DW 5000 3 leg for gigs which is good but has a broken mem lock so I have to really crank down on the collar so it doesn't drop while I'm playing and a base screw that fell out long ago. I also use a DW9000 2 leg that I only use at home because I HATE it. If I move it an inch over from where it is the thing rocks back n forth like crazy when I'm footing it. I shouldn't have to mess with it for 10 mins. every time I set it up somewhere. Also, the floating cam action gets really annoying when playing slower 8ths with the foot since the top cymbal floats up and down so much that when the cymbal is floating downward at the same time as the foot is coming down, there is no spring resistance making for a constantly inconsistent feel in in the pedal. It doesn't matter how tight or loose the spring is set. Oh, and the fancy pants cymbal tilter just disintegrated after a few months. Total $300 waste of money. With that said, I have to say that I'm very surprised at how nice the Dynamo feels. It's light, but very stable and stays glued to the carpet thanks to the optional spikes on all 3 legs. It takes more pressure to hold the cyms very tight compared to the DW9000 but I can handle that if the pedal feel is consistent and solid. I don't intend on gigging with it as I don't want to put it to the rigors of my hardware bag since it's original to my 71 Slings but, after using it at home with a very active HH foot, I have nothing but good things to say about the Dynamo. I may even get another to use on gigs. It would definitely lighten up the bag.
Sorry if this sounds like a rant on the DW 9000 2 leg. It's intended to be a rave about the simplicity and excellence of the Slingerland Dynamo. I would've never guessed these stands were so great based on the lightweight appearance.
