My four-ball urethane arsenal would be:
Scarlet Quantum, box condition, drilled label leverage
Red Hammer, light polish, drilled CG-axis
Another Red Hammer, polished, drilled with label shift but no XH
Black U-Dot, glossed like a marble, CG in grip center
I already have the axis Red Hammer in the bag. The other three are still in the closet, undrilled, waiting for the day when resin and particle equipment get banned. No, I'm not holding my breath.
