The First Blood is the first step in a new direction for Hammer’s high end products. This ball marks the end of the Taboo line and the end of use of the legendary Black Widow Gas Mask Core. The new core has a lower RG than the Gas Mask core, while providing just a tad less differential. This new core is paired with a brand new coverstock named Next Big Thing. A new finishing process only makes sense with the new cover and new core of the First Blood. The Powerhouse Factory Finish is applied to a lower 1500 Abranet.
