I got the ball drilled last night. I bowled games with both the Pure and the Pure Adrenaline. The Pure has a rounded arc to the pocket. The Pure Adrenaline has a down and snap to the pocket. On shots where the Pure hit the pocket and left a 10 pin, the Pure Adrenaline hit the pocket and still managed to kick out the 10 pin. That's been my biggest complaint about the Pure, too many 10 pins on certain pocket hits. I'm planning to use the Pure Adrenaline in league tonight. I'll let you know how it goes.
