- Tempo

First Impressions
The Track Tempo presents itself as a shiny, emerald-green pearl ball with a symmetrical core. It features the DR-5 Pearl coverstock and the new Tempo Core. The specs show a 2.560 RG and a 0.038 differential in the 15-pound ball. The surface comes polished with 500 and 1000 Siaair plus Crown Factory Compound. These specifications place the ball in the medium RG range with a low-to-medium differential, which should provide controlled length with moderate flare development.
Comparison
The core construction with these numbers should allow the ball to glide smoothly through the heads and the transition before releasing its energy on medium to light oil volumes. Compared to more aggressive symmetrical cores like the Storm Phaze II, the Tempo Core shows a noticeably more subdued character. The proven DR-5 Pearl coverstock promises good length with a strong backend hook, similar to the performance of Hammer Black Widow balls, but with less early traction due to the polished surface. The combination of medium RG and low-to-medium differential positions it between controlled house ball options and more aggressive performance balls.
On the Lanes
The Tempo is designed specifically for situations when the lanes start to break down. Its ideal window is on light to medium oil patterns. The Tempo Core should provide medium flare development and thereby allow more control through the heads, which makes it a good choice if you throw the ball at slower speed. Track fans and bowlers looking for a core-cover combination that glides smoothly through the heads and midlane will reach for the Tempo as soon as the lanes begin to break down. Its character makes it particularly valuable as a transition ball in longer sessions or as an alternative to more aggressive options when precise control matters more than maximum hook.
