The famous centripetal core is partnered with urethane this go around and we are not disappointed with this one. Benchmark core meets benchmark cover for excellent control for those who like to keep their angles in front of them. The IQ Tour 78/U will be excellent for those who bowl on patterns and need variation from the Pitch Black. I found the IQ Tour 78/U to be smoother than the Pitch Black and is great when control is needed and angles need to be in front of you. This ball will be excellent on short to medium sport patterns.
