Brunswick is offering a very limited release of this special edition bowling ball. The Brunswick Inferno Blue Flame is only available in 15 pounds and when they are gone, they are gone. Brunswick has combined the Relativity Hybrid coverstock with their Inferno Low RG core then they finish it with a 4000 grit pad. The combination allows this ball to rev early and then break at the mid-lane for a powerful and continuous backend reaction. This bowling ball's strong and controllable hook motion is ideal for rev dominant bowlers and players with slower ball speed when matched up on medium to medium heavy oil conditions.
