Borrowed a lead pot and a mold from a friend to pour some 1/8 round jigheads. Mold calls for Eagle Claw size 1 or 1/0. I am going to pour some with both sizes, but I mostly use large jigs (2 inch beavertails). What is the difference in the 570 vs. 575? I want the longest shank of the two. Is that the difference, or something else? I know, dumb question, but I have to order, so I can't look at them in person.
