No. Storm lists different numbers for the lighter weights: the 15 lb Storm Phaze 2 Pearl is 2.480 RG and .051 differential, while the 13 lb is 2.590 RG and .045 differential and the 12 lb is 2.650 RG and .035 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.
