The RPM Swirl offers the great control, power and high revving performance of the original Ninja RPM plus a longer skid and harder backend reaction for better pin carry. By combining the tremendously successful, patented RPM Ninja core and double shell, with Reactathane II, AMF has created a ball that will perform well on a wide range of lane conditions.

Back when I was learning how to hook a ball, I drilled this Gem and did not know how good it was and how much I'd miss it if it was gone. I threw my first 700 with this ball and a high series of 796 and a few 279's along the way, then when my Ego hit an all time high, I decided this ball did not cover as many boards as I wanted so like many Moron's, I sold it! Here I am 15 years later with 17 - 300's and 3 - 800's but I can't help thinking that I would have shot a lot more high games and series with this ball! Good ball's come and go, the AMF Swirl will stand as my favorite ball of all time!<
