Radical: Slant HD

Manufacturer’s Intent: “Slant HD is a strong asymmetrical core ball that uses the soaker additive which removes the oil from the surface 54% quicker than balls without this enhancer,” says Phil Cardinale, Radical’s president. “The Slant HD uses the same booster core as in the original Slant [May 2011], but we have increased the density of the flip block, boosting the differential.”

Core Design: The Slant HD (high differential) core boasts a 2.47 RG, a .054 differential and a .026 mass bias strength. The strong intermediate diff (mass bias) can help shape the motion path dramatically. We saw a maximum of 7 inches of track flare. Our favorite “oil” drilling used a 60×5.5×20 P3 dual angle layout.

Coverstock: The Slant HD (highly defined) soaker cover formula responds quickly off friction. The HD’s colors are a fusion of midnight and light blues. The factory surface is 1500-grit polished. Oil traction is limited with this finish, yet can be altered easily for heavier oil volumes. The factory finish produces a low Ra value.

Test Results: Having been impressed by the three earlier Slant balls (solid, October 2011; pearl, May 2011; and hybrid, January 2012), we were curious what the new HD edition would offer. We used our standard dual angle control layout of 60×4.5×40 for comparative purposes. This layout positions the pin above the ring finger for our 300 and 425 rev rate testers. The Slant HD provided similar length to the pearl and hybrid Slants, but easily flipped harder off the spot. The increased core differential and HD cover formula were the contributing factors for this increased response. The Slant HD is a true skid/flip ball for medium to medium-heavier oil volumes. Speed-dominant types could require a touch of surface scuffing to lessen front- and mid-lane length, though. Total hook was generally 1 to 3 boards stronger than the other balls.

When to Use: Being a true skid/flip ball, the new Slant HD may not give great looks on some fresh or Sport patterns where control and predictability are needed. Radical offers the Times Up lineup for those needing control instead of a dynamic back-end ball motion. Yet on patterns where length and an aggressive breakpoint were needed, we saw that and more — great pin carry, one of the most angular breakpoint shapes and an extended amount of usability as the pattern went south.
