The chronic is a good choice for flat patterns, at least for me last night on viper. I drilled mine with pin in the ring finger, my PAP is 5 over 0 up/down.
It's a smooth rolling, mid lane reading ball. It was great the first two games when the pattern tends to put me in over under hell. By the third game I had to start moving left aND needed to change balls to maintain angle to the pocket for strikes.
