I have a Yamaha rack for the hi-hat, but I had problems with the old clutch. Tore up the thread so it no longer held the top cymbal. I decided to buy the LC 930 clutch, because it seemd to me a good quality. I can say that I have no problems with it. The part which lies the top cymbal is without threading, so it can't be destroyed. For further consolidation can be tightened the screw on top and on bottom of the clutch, which is a good thing, only problem is what you always need to have the drum key with you when you are setting up hi-hat cymbal.
