Although the company is mum on the details, the new head appears to build on the theme of the Epic, which was the top-selling driver on the market for much of 2017. The success of the driver helped push Callaway to more than $1 billion in sales for the first time in nine years. The company raised its guidance for 2018 sales in August to $1.210 to $1.225 billion.

The Epic was the company’s first driver to employ “Jailbreak Technology,” where two bars join the crown and sole directly behind the face. The intent is to stiffen the body and concentrate more flexing in the face for increased ball speed across a wider area. The Epic Flash drivers all feature the distinctive sole ports that frame the words “JAILBREAK TECHNOLOGY.”

There were several versions of Epic Flash on the conforming list this morning, including a Sub Zero model and a left-handed version. According to each driver’s description, the words “FLASH FACE” appear on the face.

Based on the images of the Epic Flash on the USGA’s conforming list, the new drivers will feature a sliding weight track in the rear perimeter of the sole, similar to what was on the original GBB Epic introduced in 2017. The Sub Zero version appears to feature an additional weight in the front portion of the sole.

With their appearance on the conforming list, it is possible the drivers could be put in play at events this week, including the Web.com Qualifying Finals in Chandler, Ariz., or the South African Open hosted by the City of Johannesburg on the European Tour.
