Performance Analysis

Performance Analysis

The Hammer Pure Envy was designed as a heavy oil powerhouse, featuring the proven Launcher Asymmetric Core paired with Hammer’s HK22 Cohesion Hybrid reactive coverstock. With an RG of 2.50 and differential of .055, plus a substantial .021 mass bias differential, this ball creates significant track flare (5-6 inches) that helps it continue reading the lane even in flood conditions. The asymmetric core design provides the angular motion needed to recover from deeper angles while maintaining excellent pin carry.

The HK22 Cohesion Hybrid coverstock strikes an effective balance between the early rolling characteristics of solid reactive and the length of pearl reactive coverstocks. The factory 500/2000 grit finish is quite aggressive, making this ball grab early and create a strong midlane read. While this limits its versatility on lighter oil patterns, it excels in its intended heavy oil environment. Bowlers may want to consider surface adjustments or adding polish for medium-heavy conditions, but the Pure Envy truly shines when the lanes are challenging and other equipment starts to slide.

Here you go, I know we always say this is the ball. Well Hammer has done it again. The Pure Envy with HK22 and Cohesion additive gives this ball great motion and traction. I used out of the box at a tournament the 1st day for the 1st 4 games, then used it in league in a different center and then in league in another center and the ball response was great in all 3 events. I do have it drilled aggressive and am just letting the lane shine do the work. It definitely will be going to a few up coming tour events.

This ball is phenomenal! Very strong for the fresh! Definitely first ball out the bag. Bowled 300 with it a week after purchase

Bob Newman Sep 19, 2024

I am a big fan of the Envy line of bowling balls. The Envy Tour is my go-to ball when the lanes are tough. The Envy Tour Pearl is a favorite of mine when the lanes have opened up and you need high scores. The Extreme Envy is my favorite heavy oil, or long oil ball. I'll throw in the Hammer Effect also because that is my favorite ball when I need to get super deep on the lane and play 5th or 6th arrow. Now hammer is adding the Pure Envy which has attributes of all of these pieces. It has a dull hybrid cover, but that cover has the HK22 & a cohesion additive that was introduced in the Effect. It has the original Launcher core which is slightly different than the Launcher LRG in the Extreme. This ball is a big oil ball that is a little cleaner and more continuous. I have about 5 or 6 games on mine and so far, I am letting it lane shine. The shape has just gotten better and better so far. This one has a good chance to be special.

I am a huge fan of Hammer's products and have been using the Black Widow 3.0 and the Effect since they were first released and as much as they improved my game nothing comes close to the effect, pun intended, that the Pure Envy has had. I has quickly become my first ball out of my bag and usually the only one with few exceptions. Even when I am a little off this ball still absolutely crushes.

Chris Monroy Oct 11, 2024

The Hammer Pure Envy released a couple of weeks ago. It features the same Launcher asymmetric core found in the original Envy wrapped by a black/pink/purple HK-22 cohesion coverstock. Box finish is 2000 Siaair and the videos were shot on fresh THS. I've also used the Pure Envy with good success on higher volume, 45 foot 4:1 challenge pattern. For comparison, I threw an original Envy at box finish with a comparable layout. Compared to the original Envy, I definitely see a little more length and a stronger backend. In practicing with both pieces on the same pair, I got the Pure Envy a little wider and it came back with a little quicker motion off the spot. The original Envy is a bit earlier and smoother from what I saw. That being said, the Pure Envy, like other releases in the Envy line, are designed for higher volumes of oil. I see this new Pure Envy as a good choice for any higher volume patterns and depending on the bowler's speed, could be in play on a variety of pattern distances. The Pure Envy is readily available, see your pro shop for more information.
