48 Hook 16 Length 15 Breakpoint Shape
Manufacturer’s Intent: “The new Wisdom will suit players with slower ball speeds and with rev rates that find them fighting too much down-lane hook,” says Eric Thomas of 900 Global. “Also, bowlers looking for a pearl ball with a smoother reaction, as opposed to a hockey stick flip, will fall in love with the Wisdom.”
Core Design: The Wisdom has a modified symmetric core design with a higher RG and lower differential than the original Wisdom (July 2011). The RG has been raised from 2.54 to 2.57, while the differential was lowered from .043 to .035. These changes help add length and lessen back-end motion for most release styles.
Coverstock: The Wisdom’s deep red and silver pearl cover provides the visual for the S65 reactive cover base. This medium strength cover provides adequate traction for the new core shape. The Ra level measures low with the OOB factory polished surface.
Test Results: The Wisdom’s trademark roll is easy length with a smooth move at the end of the pattern. We saw limited oil traction with a moderately quick dry-lane response on our Sport and house test patterns. There were no skid/flip tendencies except on the heavier oil patterns, for which the Wisdom is not best suited. On all the other patterns, the Wisdom offered a controlled move with extended usability throughout the transitional phases. Senior (or non-senior) players with reduced ball speed will enjoy the lack of effort needed to get length and backend on most medium and lighter oil volumes. The .035 differential will keep track flare in check, thereby allowing for extended use as the oil goes bye-bye.
When to Use: Use when trying to control the later part of medium and lighter oil patterns. We felt the Wisdom carried very well as the lanes became drier and drier. Even as we ventured left of 20-board, our high (400), medium (300) and low (220) rev rate testers all still saw above-average pin carry. As with most symmetrical core shapes, longer pin distances will delay the breakpoint motion, thus preserving perceived back-end angularity. Our favorite layout to produce this delay in energy utilized a dual angle drilling of 70x5x45.
