SWAG created the Craze Tour Solid to offer more traction to the successful Craze line while maintaining control. The low differential Craze Core (2.52 RG, .030 Diff) and the Rage AP26 Solid coverstock polished to 4000 grit reads the lane earlier and gives more overall hook than the original Craze Solid. This results in a smooth predictable motion with enhanced midlane traction. An good choice for medium oil conditions, budding bowlers and anyone looking for consistent benchmark performance at a great value.
