Hello! This is my first post here and I need some help.
I'm interested in learning the ropes of the specialized technique of fishing a live bait rig with two rods at the same time. I want to use this when pier fishing. One rod is used to cast out a heavy sinker, presumably as far out as you can get it. The other rod is the fighting rod with the live bait rig. The live bait rig is sent sliding down the anchor line of the first rod, when the fish bites, the rig breaks free from the anchor line and the angler fights the fish. All this I get. What I don't get is how the live bait rig and fighting line is attached to the anchor line that lets it break away when a fish bites, but allows it to also stay on the anchor line while sliding down to the water.
If anyone is familiar with this technique, please let me know how it's done first, and then let me know whether it's worth the trouble, whether it works, or if something else is better.
I'm going for the biggest fish I could possibly catch off a pier (Kiptopeke) in mid October.

Thanks for the help!
