Amf: Incinerate Pearl Hook 51 • Length 15.5 • Breakpoint Shape 15


////////////////////////////////////////////////////////// ////////// Manufacturer’s Intent:


“The Incinerate Pearl is all about one thing: backend,” says AMF/900 Global VP of International Sales, Dave Smart. “The original Incinerate [June 2013] is the biggest midlane-hooking ball we have ever devel- oped, created by the F90 shell. With the Pearl, we raised the RG and used a polished F73 coverstock, making this the perfect com- plement to our heavy oil mon- ster, and providing the most backend AMF has ever developed. When you need to get in and open up the lane, the Incinerate Pearl will keep coming back.” Core Design: AMF decided to raise


the RG of the Tower symmetric core to 2.54 and keep the differential at .050. This ensured added length and down- lane continuation from this core. We saw a slightly smoother back-end shape from the 5-inch flaring core. Coverstock: The aggressive F73


pearl formula is colored with black and orange for a festive look. Factory sur- face is highly polished for easy length. We measured the Ra at 1.5, with an effective surface grit of 5400. Response


felt the Incinerate Pearl would be a skid/flip ball for medium oil patterns. Our opinions changed as


we saw no skid/flip motion on any of our test patterns. We did see the ball perform well, though, on many medium patterns, with a strong and smooth-arcing finish. The test group also felt the smoother shape was easier to control and stay with through normal lane tran- sition. The only annoyance was with the


highly polished finish, as this created a tad too much length for some. We remedied this with a fresh 1000-grit sanding prior to applying the factory polish. Both hitting and carry power were very good with either surface. When to Use: Since the Incinerate Pearl


hooks five to seven boards less than the original sanded Black Incinerate (58.5 hook rating), uses will be on lesser oil volumes and for those with slower ball speeds. That said, the Incinerate Pearl is still strong, just not on heavier oil or longer patterns. It complements the original perfectly when the pattern starts going away, and players are still looking for an aggressive pearl with some down-lane attitude.

900 Global: Eagle Pearl Hook 52 • Length 15.5 • Breakpoint Shape 17


////////////////////////////////////////////////////////// ////////// Manufacturer’s Intent:


“900 Global fans have been waiting for a pearl version of the successful Eagle series [Eagle, May 2011; Black Eagle, March 2012; War Eagle, March 2013], and it’s finally here,” says 900 Global’s VP of International Sales, Dave Smart. “The tried and true Eagle/Break core is paired with our S70 Pearl coverstock, which provides good length but a heavy roll in the midlane due to the lower RG. You’ll find the Eagle Pearl to be a consistent winner when the lanes begin to transi- tion and oil moves down the lane.” Core Design: The Eagle pearl utiliz-


es the proven “Break” asymmetric core design. The RG is 2.48, the differential is strong at .058, and the PSA hefty at .024. We saw nearly 6.5 inches of max- imum track flare with a strong 3.5-inch weight hole-down drilling pattern. Coverstock: 900 Global decided on


the medium-strength S70 pearl cover for the new Eagle. This Eagle edition is a gorgeous black pearl. The factory finish is highly polished at 4000 grit. Response time is moderately quick,


and oil traction is limited. The Ra is 1.6, with an effective surface grit reading of 5400, great for medi- um volumes. Test Results: The Eagle


series offers a strong asymmet-


ric core shape with an aggressive pearlized cover designed for most medium-volume oil patterns. The polished cover prevented us from using it in too heavy of a pattern, as we often saw over-skid as a result. The Eagle pearl struts its stuff mainly off friction, not in oil. Players can expect added angularity


and easy length through the fronts. The core also is quite release friendly, and hit- ting power is impressive. When to Use: We created an ear-


ly-rolling, smooth arcing motion with a 35x4x65 dual angle layout, combined with a light surface sanding. This arcing layout matched up best when we played outside lines from the 12th board to the gutter. We also created a long and strong reaction with a high-ratio dual angle layout such as an 80x4x20. This layout choice matched up when we ventured well inside the track area and sent-it and bent-it. Our final all-purpose layout, a 50x4x50 dual angle, helped blend the two reaction extremes perfectly.
