Hi Ryder,
Most hardware will move a bit, when the cymbals are hit.
Normally not a big deal, as long as it does not interfere with what you want the cymbal to do.
Try riding the crash in a steady pattern and see what really is going on.
Something tells me that you might have your cymbals quite tight in between the felts. Personally I like the cymbals to sit real loose.
I had a big cymbal (20" heavy Ride) supported from a stand that was as flimsy as a music stand. (I had forgotten my proper stand)
It still worked okay but it was a bit scary, I have to confess.
Other wise, I agree with Tainojim, The
Gibraltar stands are excellent and imho the best value for money.
Cheers and Happy Drumming
