The Mastermind is the latest Pro Performance release from Brunswick. It has a new core design and new coverstock. These two elements come together to give users giant amounts of hook on heavy oil conditions.

It was no shock to any of our testers that a ball this rough and aggressive would be best on our heavy oil test pattern. Stroker and Tweener felt more comfortable on this pattern with the Mastermind than they had with any previous...

The Mastermind provides a sneaky amount of movement at the breakpoint for a ball at such a rough box finish and a low RG core. Bowlers on heavy volumes who want a ball with some movement down lane will like the reaction the Mastermind provides.

The rough box finish is officially 500 followed by 1500 SiaAir pads. This rough finish easily creates friction, even on our slickest test pattern.

This ball can still move when it gets out of the oil pattern toward the end of the lane. This motion will come in very handy on heavier patterns.

The Mastermind is right up there with the biggest hooking Brunswick products in recent history. This ball will be the one to go to when nothing else in the bag is creating enough movement.

Strengths: The ability of this ball to create traction is its biggest strength. We have not seen anything close to this much hook from Brunswick besides the Paranormal Aura.

Weaknesses: Dry lanes will have this ball in the bag quickly. There are plenty of weaker options than trying to tame down this hooking monster.

Overall Summary: The Mastermind is the Brunswick ball to own for heavy oil patterns. This ball can hook on anything.
