I know some drummers who love them. A friend of mine uses one (I just heard her play two weeks ago) and it sounds very good.
I had one for a while, but it was not my favorite. I can't remember it well enough to give you a good review though. Sorry. My son got it (ultracast) from me, then he took my Dennis Chambers signature snare (one of my favorites) and that's what he plays. The ultracast is relegated to his backup snare.
It is the 5" or 5.5" depth.
Hope this helps.
You might check Pearl Drummers Forum. There are dozens of threads on the Ultracast. Or just ask on there.
