I threw the old Ching stuff for quite a while (non-dimpled).....the Sniper and the Bomb were in my bag for years, but when they ceased making them (or at least carrying them in the Memphis area), I switched to other molds.
Historically Ching Discs have always been good product - they are DX like but seem to made of a more dense plastic....Hadn't seen a "non-gizmo" Ching release in quite a while......
Probably worth the test......Griff
