Core Design: The new Edge family of cores for the 919C is called Blade. Its RG rating of 2.53 is medium, a Diff of .049 and a mass bias of .019 can control the amount of track flare and motion shape. Testing showed the core revved up much more quickly than the 2.53 would indicate. Additionally, the C now stands for continuation, not control, for this ball.
Coverstock: Track’s newest cover formula, the Haze HP9C, incorporates a hazed-look into the coverstock which can change appearance through normal usage and/or temperature fluctuations. Track says this has no bearing on overall ball performance. The cover is sanded with 500, 1k, 2k and 3k Abralon pads, which create good oil traction with a moderately quick response off friction. Colors are a blending of blues, reds and silver.
Manufacturer’s Intent: Paul Figliomeni, Track’s Brand Manager, shared this: “We have a new core and cover that are perfectly matched for all styles of players. It’s the best ball to come out of Ebonite International’s Track brand, period.”
Test Results: Track’s 900 series of balls are the strongest in regards to core design and cover strength. My test staff concluded the 919C is the best rolling and most usable ball in that series. Normally, as the lanes break down, we’ve had to bag the other 900’s due to an early read or over-hook situation. But the 919C was easier to stay with longer, plus it displayed above-average pin carry as the oil left the building. This can be a common occurrence with any manufacturer’s super-hookers as oil depletion occurs. The 919C is a benchmark type roll with a little extra total hook and extended usability.
When to Use: The 919C with box finish comes to play on medium to medium-heavy oil volumes. Extremely oily patterns required a 1k grit sanding. We could play near the friction with a light polish, or we could play just inside the oil line with box finish or lower. Playing deeper inside angles would work best only for Michael Fagan release styles due to its more gradual response to friction. Our favorite layouts utilized 4-5” pin distances above the fingers.
