I ordered an 18" a long time ago (like early 2015) and it took forever to be delivered (it was while the DW thing was happening, was the excuse). I've been using it now for 4 or 5 months and I'm really loving this cymbal. I already have 16" and 18" HHX Evo crashes, and I also have an 18" HHX Ozone, (along with a couple others crashes I don't use), but the Aero is becoming my favorite. It's got a fast decay, and is slightly trashy like the ozone (but not nearly as pronounced ). It's higher pitched than the ozone too, more like my HHX Evos, and it blends nicely with them. Just wondered what other peoples experience is with AAX Aero? I think I might need to pick up a 20".
