That's a CZX Studio. Great drums!

I have a Custom Z in maple. Never had a chance to the birch drums in person. I have heard they sound great.

IMO, birch shells are an acquired taste. In my experience (I had two Tama Starclassic Performer sets and sold both), the birch shells were very dark, rather harsh, and they did not project well in live situations. They were fine if you mic'd the whole set, but who needs to do that on smaller gigs? Maple shells are warmer and have better projection generally, and that's what I prefer.

Birch shell drums excel in studio situations however, so it depends on your needs. I believe Premier drums were almost always made of birch, as were many other Euro brands.
