1/8 oz. with 4/0 hook would be good also one of the most popular swimbait heads in the group that buy from me is the "J Will Swimbait Head"a mold to make something similar would be great1/8 oz. - 3/4 oz.4/0 and 5/0 hooks seem to be the ticket
Look at the new shad head with wire keeper mold, this is a great head design by itself or on the A-rig.
