Dark Matter are heavy and totally un-lathed.  While not at all gongy, they certainly can ring a bit more than a traditional lighter cymbal.  Stick response is fantastic.

They currently come in two flavors, the Dark Matter Energy Rides and the Dark Matter Flat Earth Rides.  The grand-daddy of the Dark Matter family will be available shortly, the Dark Matter Moon Rides:  these are quite heavy, very dry and cutting.  Not for the faint of heart.

Energy rides:  lathed under firing, large bells, medium weight, dry stick response.

Flat Earth rides:  lathed under firing, micro bell, flat profile.

Moon rides:  very heavy, large bells, un-lathed, double fired. Hi cutting, dry.
