It is listed in 12, 13, 14, 15 and 16 pounds, and the specs do change by weight. The 15 pound is a 2.500 RG, .058 differential and .016 mass bias, the 14 pound is 2.500, .056 and .016, and the 16 pound is 2.510, .048 and .015. The 13 pound is 2.589, .043 and .011, and the 12 pound is 2.612, .043 and .011, so the two lightest weights have a higher RG and a lower differential than the 14 and 15 pound balls.
