The most expensive plug I currently own I paid around $20.00, PlugCaster Pencil (9"). At one time I had a few Big Rock swimmers, RM Smiths, etc. Anything I paid over $20.00 I sold off. I saw no advantage fishing the expensive plugs (Rip Pluggers Rip runners and Splitters caught more, I had/have more confidence in them).
The 9" PlubCaster Pencil, which looks like it has a great finish has the top coat peel off after a fish or two.
