Original Black Nighthawk.
Honestly, any mild reactive with an Rg around 2.5 and diff around .04 and solid (no pearl) cover has been a terriffic THS ball. It gives you some length, doesn't jump right away when friction is creeping up from the burn, and is not a hockey stick type backend reaction, thus you have more control than the high diff stuff or the pearl/shiny stuff.
Such as:
Hammer Blade Reactive
AMF Nighthawk
AMF Villain
Brunswick Copperhead
Visionary Gladiator
Brunswick Wizard
Brunswick Nemesis
Storm Street Rod
Roto Grip Grand Illusion
Track Kinetic Energy
Make no mistake about it, the manufacturers know these numbers in general give great ball reaction
and the list surely goes on and on, those are just to name a few and all of them work great on a THS.
