The Jagged Edge Solid combines our new Brink Symmetric core with the Relativity 2.0 Solid coverstock to create aggressive mid-lane traction and strong backend motion on medium to oily conditions. The 3000 Siaair finish will allow the Jagged Edge Solid to handle more oil than the Cutting Edge Solid. Great benchmark motion and lots of performance for the price. ADVANCED: Performance features with a wide range of reactions for bowlers of all skill levels. TRACTION: Balls that hook earlier on the lane providing more hook on oilier conditions or for bowlers with lower rev rates. Balls with higher numbers will have more overall hook. REACTION SHAPE STRENGTH: 68 - The higher the number the stronger the reaction shape – with 1 being the least and 100 the most. Now available in even more weights the Jagged Edge is available in 10-16 lbs.
