Some think some are solids and others think some are pearls. Yet, Rich Hanson Marketing Mgr. told me in a e-mail that the Cyclone is actually a hybrid.
Regardless, the Cyclone is a lot of ball for the money. However, my wife's Cyclone (Black/Red/Yellow) is a oil soaker. I have to de-oil it every two weeks or so to keep the reaction. High maintenance ball. Otherwise, I highly recommend this ball.
