The Obsession Tour is part of a two-ball launch with the Obsession, both having a solid cover; the difference is the core. The Obsession and Obsession Tour have the same core shape; however, the Tour edition differential is .016 points lower, creating less flare, less hook, and a more controllable reaction compared to the regular Obsession.
The Hammer Obsession Tour will create a unique reaction that will allow many players to stand closer to the dry and be great for higher rev players. It uses an updated version of the Tour cover found on the Web Tour balls. Featuring DOT technology , which allows you to drill anywhere which makes this ball even tougher.
* Product Note: 12-13 lb. models of this ball use an alternate core that is different from the heavier models.
A truly innovative approach to bowling ball construction, DOT pins the low RG axis on the opposite side of the ball. This removes the weak spot in the drilling area, greatly reducing the possibility for cracking and providing for a wider range of layouts. The DOT manufacturing process marks the low RG axis with a small circle engraving.
