I had a Hammer Burn for about 2 weeks. At first I thought the yellow would be really cool going down the lane. Boy was I wrong. Not only was it one of the UGLIEST balls I've ever thrown, I couldn't read the reaction at all. The yellow is just too hard to see for me. I have a track 916AT that is red and yellow, but I made sure the one I got from my pro shop is mostly red.
