Years ago I read or heard about the advantage of using two split rings on a crankbait's rear treble hook. I just started trolling crankbaits for when the bite is tough and for some reason catch some quality fish especially in water 8' or less in lakes that aren't much deeper than 12' during late summer's slow transition to fall.

The reason for the double split ring is so fish don't have the leverage to unhook themselves especially when jumping out of the water. IT DEFINITELY WORKS ! As long as the hook set it good, they don't come unhooked especially when using zero stretch braid which allows that leverage.

Man do I hate it when a nice fish jumps and is gone!
