I make jigs for a living, and I'm sure there's plenty of ideas on how to fish them. When their using a swim bait, I swim a jig, when they drop - shot, I hop the jig, when their using a crank bait, I speed up the jig, senko bite is on, 1/8 or 1/16 oz. jig. I would tell you to always use a trailer, but there are times that you should'nt. If the bite is a bait fish bite then "GO WITH THE HATCH" a shotrened & thined the skirt or left long skirt with a trailer (single tail), it all depends on the time of year and the size of the bait fish.
Pre- spawn & post spawn - hefty skirted jig - " ME WANTA EAT? I'm a crawdad(crawfish)- (full skirted) meal type of jig with a twin tailed trailer, your choice of co., but play with the color don't relie on the "trend" try your own ideas. You might want to try a light weight jig (1/8 - 1/4) on beds. The slower fall entices them more than a fast in your face type of presentaion. Another idea, when others are throwing frogs, flip or pitch a jig into the same junk. the action of the frog will knock lose baby crawdads loose from the folige Use enough weight to, again "match the hach" and the fall per the size of tha crawdad & the water temp. I could go now for a few pages or more, fact is read, on the water, pratice, practice, practice!
One fact, a jig has cashed more checks than any other bait. Spend time, don't buy junk (you get what you pay for).
