Anyone used one yet?  Thoughts/opinions?

I just put a set of them on my PDP CXR maple kit with 12" rack and 14" and 16" floors. Clear Amb's are the reso heads.

I like it a lot on the 12". It has a nice warm sustain to it. I haven't had as much luck on the floors. They seem a little too dry for my tastes there. I just put them on and I need to work on the tunings. It very well be that I haven't hit on the tuning combo for this head combo to get them singing on the floor toms yet.
