I'm inexperienced GT angler too. For jigging, at today, I used PE 6-8 (or equivalent braided), nylon leader 140-200 lb, FJ knot or PR Knot, grommet (expecially for 200 lb leader) or swevel and aluminium crimp. For popping PE8-10, 200 lbs nylon leader or more, FJ Knot, grommet and crimp. I love grommet and crimp for leader-lure connection, even if a swevel should be more suitable for jigging to prevent twisting of line. I have to try to connect directly (whit crimp or uni knot) leader and lure (without split ring, grommet or swevel), but only for stick bait, 'cause I think swimming action should be more effective and easy.
