No. Ebonite lists different numbers for the lighter weights: the 15 lb Ebonite The Great One is 2.466 RG and .056 differential, while the 13 lb is 2.597 RG and .041 differential and the 12 lb is 2.593 RG and .041 differential. Those are the numbers of a different core shape, and the lower differential means less track flare, so the 12 and 13 lb roll smoother and hook less than the 14 to 16 lb. The product gallery shows both cores, one for 16 to 14 lb and one for 13 to 12 lb. The full table is on the product page.
