I modified it to accept crane swivels, drop shot swivels and stainless steel inserts, that I actually like best. I poured some swivels burried in the lead, some outside the lead and some drop shot type. Powder coated them flat black and baked them. They are very durable. 1/8, 1/4, 3/8, 1/2, and 5/8 oz. I'm using a Matzuo EWG hook in black nickle and black stainless steel split rings in size #2 20 lb strength as the #1 was too weak at only 15 lb strength.
