Tight lining is my favorite bait presentation method in the fall and winter months, but it is really too vast of a topic to cover in just one post or response. (1) Find the actively biting fish; (2) Present your baits above and not below those fish; (3) Experiment with differing speeds (because sometimes crappies want it still and other times they prefer it moving slowly... other times they want it moving much faster); and (4) also experiment with the double rigs and the single Carolina Rigs and also with jigging motions (using jigs and minnows) and free swimming and wounded minnow motions from your live bait offerings.
Welcome to the site from Sanford. I think you'll find this to be as good of advice as you might hope for to take you to the next level tight lining. I'm sure there will be others that will chime in too.
