I am looking to upgrade my Harris bipod from the standard feet to the phoenix tactical pod claws. I am running a Rem 700 308 LTR 20 inch on a AICS. Is there that much of a difference in size between the large claw and the small claw. Everytime I check out Triad hes out and I am only seeing the small pod claws on phoenix tactical's website as in stock. Should I wait for the large size to be in stock or get the smaller size?
