I rely on jig'n'pig for 70% of my bass. I prefer lunker lure rattleback jigs from 1/4 to 1/2 oz. , to which i use a zoom super chunk trailer. I use heavier jigs for deeper water, 1/4 for 1-5 feet, 3/8 for 3-7 feet, 1/2 for over 7 feet deep. Black, black/blue, black/red, pumpkinseed, and brown are the only colors you need, and really, black just always works...its what i have on most of the time.
I've been using plastic trailers for a few years now. I really have not found that pork catches me any more fish...even during the colder months...and plastic is much easier to use. The thing with plastic trailers is that you have to use quality ones, zoom superchunks, super soft hand pours, and zoom fat albert twin tails.
