Nice writeup! Which sinker rig was being used? The new version with the hook inline above the sinker, or the one with the hook below the sinker? Also, you don't need to got to a soccer field to mark your line. Get a premium sharpie (get a big one and put a notch in it), put your rod in the trolling straps while under way and hand count out and mark every 50 feet (or use a line counter like above post suggested). Make sure you only let out line, no weights, or jigs or you will be railing the rod in low gear for 10 minutes to get your line back. I've never had the line bleed when I applied it to dry line so just do this before you fish. Mark to 500 feet, every 50 feet. Make sure you mark every 100 feet differently (eg. 1 long mark at 100, 2 long marks at 200, etc). You also have to use a little math if your line scopes out. At 30degrees, add 15% to your line for correct depth, at 45degrees, add 30%. More than that, reel in. As for the jig hooks, the 2 assist hooks on the top are good, I also put a 10/0 or 11/0 jobu hook on the bottom. 10/0 are much easier to get in a split ring. If you tie your line to a solid ring and connect it to a split ring, then you can attach assist hooks that either have or do not have solid rings at the top. It also allows you to swap out a lure without retying.
