Here is my take on learning to fish a jig to simplify things:
1.If you can fish a T-Rig you can fish a jig, only difference I find is with a jig bigger fish will just knock slack in the line.
2. Use the same colors in jigs that you use in soft plastics, KISS principle applies here.
3. Trailers= Keep it simple here as well, chunk style and something that moves water (doubletail grub, Rage craw, Chigger craw, or something similar) and colors should match the jig skirt to start.
4. Weight = You something slightly heavier than your T-Rig. Jig with a trailer will fall slower than a T-Rig of the same weight. Don't go too much heavier as 1/4, 3/8, and 1/2oz cover most situations.
5. Try lions-cut or fine cut skirts if you want more of a finesse presentation.
To really simplify things try this jig with a Zoom Super Chunk Jr trailer.
