Firstly, this is a Tama product so it is going to be excellent. I use this with a multi-clamp attached to a boom stand for a 10" Splash cymbal which works perfectly.
The extra length is superb and gives me more options if I want to use it for different things. It is so strong that if I needed to use it for an extra crash it is more than capable. The cymbal mate topper is the easiest and quickest I have ever used, there is no need to waste time twisting the cymbal topper tight, you simply squeeze the edges and set it on and that's it tight. Done.
Extra length, strong and sturdy, not too heavy, genius cymbal mate topper. Excellent product 10/10.
