46 Hook 14 Length 14.5 Breakpoint Shape
Manufacturer’s Intent: The Fly Bullet L’s core is quite powerful and has two characteristics — asymmetric and symmetric — according to manufacturer QMR, which is based in China. This is intended to provide the ball driller with great flexibility in “matching up” the ball to the bowler who will be using it.
Core Design: The unique design shape of the negative differential Fly Bullet core offers both symmetric and asymmetric properties, dependent on which pin configuration you choose when laying out the ball. The RG is high at 2.58 and the -.057 Diff can produce nearly 6 inches of track flare, either in a clockwise or counterclockwise direction.
Coverstock: The color printed on the box for this solid reactive cover is blue and light blue, but my eyes tell me it’s a purple and white mix. The swirl pattern is unique with its long striations. The surface is sanded to 1000 grit, yet feels as smooth as a 4000 grit. We found oil traction to be well below average and response time off drier boards was moderate at best.
Test Results: The Fly Bullet L houses a first-of-its-kind weight block with above-average power, but the cover is relatively weak by American standards. That said, the Fly Bullet produced a good look on light-medium to medium volumes, providing the backends weren’t burdened with oil carrydown. We saw some amazingly strong pin action on some releases, but not consistently across the boards on this month’s five test patterns. I expect subsequent ball releases from this company to improve as it adapts its products to the American marketplace.
When to Use: The Fly Bullet will play great from outside angles on light to medium oil volumes for any rev rate. Players with high speed-to-rev ratios may need to lower the grit to 500 or lower to produce an early enough read in the midlane. High polishings will create a much later motion phase, but we’d reserve this setup for extremely dry lane use only. Our favorite flare-safe layouts put the small pin above the ring finger and the large pin just right of the thumb hole.
