No. Motiv lists different numbers for the lighter weights: the 15 lb Motiv Primal Ghost is 2.550 RG and .050 differential, while the 13 lb is 2.600 RG and .055 differential and the 12 lb is 2.670 RG and .040 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 full table is on the product page.
