Performance Analysis

Performance Analysis

The Purple Pearl Urethane is bowling’s most iconic urethane ball. The LED symmetric core (.015 differential) is about as conservative as cores get, which is exactly the point. The pearl urethane coverstock at 2000 grit gives it slightly more length than traditional solid urethane, creating a smooth, predictable arc that repeats shot after shot.

On dry lanes, short patterns, and sport conditions, the PPU does what no reactive ball can — it holds its line without overreacting to friction changes. There’s no over/under, no violent backend snap, just a reliable shape that lets you focus on execution.

Who Is This Ball For?

Every competitive bowler should own a Purple Pearl Urethane. Tournament bowlers use it when reactive is too unpredictable. League bowlers pull it out on dry backends. Control players and strokers love its smooth, arcing motion. With 5,148 units sold, over five thousand bowlers can’t be wrong.
