No, I don’t understand why Hammer doesn’t bring back the Arson core in weights 14 to 16 pounds. Hammer uses the Arson/Sauce core for 13 pounds and lower. Per Mitch Beasley, this is done because Hammer has found the Arson core to have a more consistent roll in the lower weights. I have found it to have a consistent roll in the higher weights as well. Loved the Arson Low flare.
