Has anyone ever trimmed a Berkely Havoc Pit Boss to use as a jig trailer? I just recently thought of this idea and was wondering if anyone had tried it before.

You could do that if you want to. However Berkley also sells the Havoc Pit Chunk. I have both and I expect them to work just fine in about 40 days.

It does work but they don't stay up the hook very well after a fish or two, the pit boss chunk works much better if you're just planning on using them as a trailer.

What he said.  It's been such a popular jig trailer that they made the chunk version with a flared end to help raise a jigs skirt.
