I have only done the full rigging process a few times but I just received a couple new eel squid jig heads made from tin that are similar to this bob jig. I got it from NJ tackle (but it is made by diamond tackle). There are TIN and are lighter then lead and have eyes. A pic is below but a link is :

The reason I like these is the hole in the middle which should puff up the body. We will see. Eels near the bottom generally do well.
