50 Hook 15 Length 15.5 Breakpoint Shape
Manufacturer’s Intent: “The combination of the aggressive Korrupt core and a pearl coverstock make the Heritage one of the most aggressive pearls in the marketplace,” says Tony Martin of Lord Field. “They give it a distinctive breakpoint and consistent reaction that a bowler can have confidence in. The straight lines in this weight block help make the motion shape on the lane.”
Core Design: The Heritage houses the powerful Korrupt asymmetric core. The 2.47 RG is low and the differential medium at .047. The mass bias strength is very strong at .024. This mass bias allows for more motion shape options per individual. Have an IBPSIA ball driller assist you for best results. We saw a maximum of 5.5 inches of flare.
Coverstock: The Heritage cover is called Proton reactive. It is sanded with 1000 grit and polished. The red and blue pearl blend is eye appealing, as are the engravings. This formula responds quickly off drier areas and displays limited oil traction at box finish. The Ra level is medium due to the 1000 grit below the polish.
Test Results: The Heritage’s strength is in its asymmetric core shape and numbers. The .024 mass bias (more accurately called the Preferred Spin Axis, or PSA) can help create a variety of motion shapes for any style bowler. The polished pearl reactive cover eased the Heritage through lighter oil concentrations prior to the strong arcing, almost flip, breakpoint shape. Most bowlers will see more push and backend pop than from the Nasty, which will be good for lighter and broken-down lane conditions. We also felt that the Heritage did a good job through oil carrydown, with little trace of down-lane wiggle.
When to Use: With the Heritage’s aggressive late-lane motion shape, down-and-in players should opt for the Lord Field Nasty or consider weaker layouts to lessen back-end flip. Those interested in utilizing the Heritage’s strength should apply their favorite long-and-strong layout choice. The box finish matches up primarily on light-medium to medium oil volumes, but the core can modify the shape. The Heritage and Nasty complement each other very nicely.
