I specified this assembly on two drum kits I had custom made and agree with another reviewer that bass drum shell mounted cymbal arms do not affect the sustain in the least. I grew up using them (started playing in 1963 when every bass drum came equipped with one), and prefer the convenience and the fact that they get my ride cymbal right where I want it - close.

That said, I did have problems with this particular assemble leaning if the tightening screw backed off in the slightest, which was more often than I cared for.

See my review for why and also for one issue I had with installing it.

Back to this one: the mounting bracket that ships with this is as solid as a rock and is engineered to hold just about anything inserted into it. It is also hinged, and will hold 12 and 10.5 MM arms. The arm that ships with this assembly is the weak link in my opinion (it's 10.5 vs the DW's 12.5 MM diameter.)

The main point of comparison between this assembly and the DW is price. The DW is nearly twice as expensive, but - and this is my personal opinion only - I think the additional cost is worth it for the peace of mind it gives me knowing that a cymbal is not going to lean or fall over while I am playing. Granted, I have never had one fall over, but I have had them lean, and I am a light hitter who plays mainly jazz. For the record, my right side ride sizes range from 21" (K Custom Special Dry Ride) to various 22 and 24 inch rides, most of which are relatively thin and light.
