I recently drilled the Brunswick Swarm up for myself. I put the pin above my ring finger and the cg 1″ off the center of the grip. I tried the Brunswick Swarm on a fresh oiled lane, about a 38′ house pattern. I’m more of a down and in bowler and a stroker; this ball worked great for that type of shot. I was very pleased to see how well the ball got down the lane and then turned pretty hard on the back end. I like this ball in medium to dry conditions. On a scale of 1-10 I would rate this ball at an 8.
