The AMF Grip gives rev-challenged bowlers all the extra help they need. The strong reaction to dry is ideal for those types of players who need extra help from the ball. When we saw that the cover of this ball was F64, we thought it would be pretty close to the Double Clutch. We couldn’t have been more wrong. The combination of the lower RG and higher differential combined with the surface change really makes this ball a monster.

All three testers preferred the Grip on our heavy oil pattern. The extra oil in the front allowed the Grip to store energy for the back end. Both Stroker and Tweener liked this one a lot. Cranker had to make surface adjustments much
