None of Brunswick, DV8,or Radical make a pearl urethane spare ball like the Mix. One of the generic plastic balls is about the only option.

For the Pitch Black there's only the True Motion and Tactic Control. I think the former might be closer... but they're all typical urethane balls.

Nothing quite like a Hustle INK. A Rhino might be the closest, but it's still not the same. I think Radical is coming out with a new Rack Attack this summer and that might be a better bet. Intel could be somewhat in the same area but it's stronger and earlier.

The Street Fight is an interesting ball with that high RG and strong cover. I would go with a Beyond Ridiculous to replace that one. Maybe a Cutting Edge Hybrid. Ludicrous. I don't know, the Fight series were so specific for how they rolled for different bowlers.

Idol is in the same category as the INK. Nothing quite compares except the Idol itself. Well, maybe a Chaos but that's from Columbia 300 so it's out of this question anyways. Uhh... maybe a sanded Fearless?

The No Rules is probably the easiest one to replace. A good ball but nothing exceedingly special. That cover was/is cleaner than expected so I might got with a Hitman Enforcer or Tenacity Grit. A Conspiracy with surface would be good too.

Sure Lock... probably a Katana Dragon. Maybe the new Kingpin Rule but I want to see more of it.

Ill take a different approach to answering your question. I’ll list what I think would be good pick ups for you for college bowling.

True Motion
Intel
Squatch
Katana Legend
Conspiracy
Kingpin Rule
