I LOVE URETHANE! | Brunswick Crown 78U

Brunswick Crown 78U Performance Test

The Brunswick Crown 78U puts the strongest core ever in a urethane ball. The Tiered Hexagon core at .046 differential — higher than most reactive balls — in 78D urethane at 1000 grit creates a urethane ball that's actually 'usable' on real conditions.

Performance Analysis

Performance Analysis

The Brunswick Crown 78U challenges everything we thought we knew about urethane bowling balls. By placing the Tiered Hexagon symmetric core — with its .046 differential — inside 78D hardness urethane at 1000 Grit, Brunswick has created a urethane ball with more hook potential than many reactive pieces on the market. The 78D hardness keeps the ball predictable and controllable while the core provides the energy that traditional urethane balls lack.

On sport patterns and shorter oil conditions, the Crown 78U shines. It reads the midlane with more authority than a typical urethane ball, giving bowlers the control benefits of urethane without sacrificing the ability to actually move the pins. The 1000 grit finish provides early traction while the smooth, arcing backend motion stays consistent shot after shot.

Who Is This Ball For?

The Crown 78U is designed for tournament bowlers and control players who want urethane that actually hooks. If you’ve ever thrown a Pitch Black and wished it had more core strength, this is your ball. Sport pattern specialists will find the combination of urethane predictability and strong core motion invaluable when the margins are tight. It’s also an excellent option for league bowlers on shorter patterns where reactive balls are too much.

Brunswick has added a PBA legal urethane option to the lineup. It has the tiered hexagon core which means this urethane ball will flare. I practiced on a THS and threw the Purple Hammer, Black Hammer Pearl, and Crown 78U to get a feel for where this ball fits. I only have about 3-4 boards difference between the three balls with the Crown 78U fitting right in the middle. It is a little later but a little more angular down lane than the Black Pearl. As you know with urethane, carry is key and that little more angular can make all the difference. This will be a good piece to have in your tournament arsenal, especially on short oil patterns.
