Performance Analysis

This overseas version of Hammer’s famous purple urethane is a stranger spec sheet than it first appears, and the strangeness is the appeal. Solid urethane at 1000 grit is the classic short-pattern control cover: it reads friction early and gently, never over-responds, and blends out wet-dry transitions that send reactive balls sideways. But underneath sits the FAB Asymmetric core with a .051 differential and a .014 intermediate differential, genuine big-flare asymmetric numbers that most urethane balls never get. The high 2.55 RG keeps the package honest, delaying the rev-up so the ball still glides through the fronts, which is why length rates a 7 despite the dull surface.

The result, by design, is urethane motion with more shape and more drive than the category usually offers. The 5 backend rating confirms there is no sharp corner here, just a smooth, persistent arc, but the core’s flare lets the ball keep gripping through the pins, which explains the surprisingly strong 7 pin action score next to a 6 hook rating. Video reviews of Hammer’s purple urethane family show that signature on dry to medium-light conditions: the ball simply refuses to do anything sudden, while still carrying better than flat-core urethane has any right to.

The 8 versatility rating is the headline number. On burned lanes, short patterns, and broken-down house shots, this profile plays almost everywhere; the one place it has no business is real oil volume, where urethane traction runs out fast.

Who Is This Ball For?

Two groups get the most from this ball. The first is two-handed and high-rev players on drier conditions, the bowlers who generate so much hand that reactive equipment becomes unmanageable when friction shows up early; the urethane cover absorbs that excess motion while the FAB core preserves enough dynamics to carry. The second is league bowlers whose houses transition hard, who want one predictable piece to finish nights on, and who occasionally want a controlled ball for tricky multi-pin spares. On short tournament patterns, this style of asymmetric urethane is a legitimate primary strike ball.

Skip it if your fresh has medium-heavy volume or more; a 6 hook rating from a urethane cover means there is simply no traction reserve to call on. Discontinued status is the other catch, since finding one now means hunting the used market. For the right bowler on the right condition, though, this is one of the more distinctive motion profiles Hammer has shipped.

Bought this for my son as a 2 handed bowler this ball really complimented his style very predictable for a high rev player. I've thrown it thumbless myself and now want one for myself lol

Compliment to the asymm red hammer urethane pearl. I drilled them exactly the same so that the surface finish is the only variable. Red Pearl urethane gives length while the purple solid urethane gives hook on the same line with same execution Start with the purple solid in heavier oil and switch to the red pearl when the line dries a little and starts over-hooking

For too long have I sat in the background— watching…waiting— as my league team dominates and I hold us back with my pitiful bowling skill. After purchasing this ball I can gladly say that my numbers have improved dramatically. I can’t wait to defeat Edna and the rest of the Pocket Pounders this Wednesday using my overseas purple hammer (•̀ᴗ•́)و

Gregory Starks Nov 12, 2023
