What's Different?

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.
