The IQ Tour is an amazing ball for all types of bowlers because of it's versitility. This ball is smooth, controlling, reads the lanes well and allows you to controls the back end. I would recommend this ball for medium to heavy conditions. It clears the front part of the lane and still responds, comparable to a pearl ball. Mine is drilled pin up and I have adjusted the surface to 1000 abralon using a surface factory machine for slicker conditions.
