Thanks. I don't know if there's much of a difference, but, after watching a lot of demos, I had the impression that the patina (raw copper) version was crisper and more controlled (could just be the eyes playing tricks on the ears). I had a Joyful Noise Anchored Copper for a while, and for a while I liked it better than the Ludwig, but then changed my mind and sold that one. That one had more power, but this one (for me) has more finesse. Both have amazing rim shots, a very solid, controlled but edgy pop that's more of a sweet knock than a clang or a bang.
