"One you see the line stop peeling off the reel, reel in the slack and lift your pole tip up and drop it back down until you'll feel the thump of the jig hit the bottom..."
This is a good add Gerry. This has helped me very much when I learned it.
I also started making my own jigs and have been experimenting with different brighter colors. No solid evidence on colors working better than others yet. I tend to gravitate towards the "more natural" green, black, orange belly, or white/gold if using white crabs. Trying to match the hatch.
I have gotten fish up to 8# on the jig and no issues with being undergunned. Sometimes you gotta grab the spool a bit when they make the first burst, but you can break off a big one doing this if you are not careful so use extreme caution doing this!
Also, somewhat surprised that no one brought up using a "stinger hook" on jigs. You can snell a traditional rig hook (I use 4/0 Owner SSV) and tie some 30+lb fluoro onto the eye of the jig and this allows you to use bigger baits, multiple baits, or just put two hooks in the same piece of crab if you want. You will lose some hooks but you can also catch multiple fish too.
Started swinging less (or trying to swing less) to wait for better bites on the jigs too. I think it works.
