There are alot of variables, as far as which one is better for you. But I have experience with the bounty hunter. It was very condition specific, great on long or heavy patterns. The train with its symmetric core does seem more versatile. My uncle has a train, which he uses on fresh ths, and it is awesome for him. Excellent carry. If your looking for a ball just for true heavy oil, I would recommend the BH. But for a more versatile ball that can be used on heavy oil as well as med/heavy, I would say Train,
