I'll be the first to admit that I don't know as much as most posting on this, but...

I fish shaky heads & light jigs all the time. I virtually never go over 5/16 oz. I also almost never fish deeper than 10 feet deep in the little lakes I fish. I fish wood some, but never fish grass, weeds, etc. I use a medium action, 6'6" Team American Rodsmiths rod that is incredibly sensitive.

This is not acceptable for the way most fish jigs, but it works for me VERY well.
