Cool crankbait article

[prime89]

The Bill contributes to how deep the bait runs and also the action of the bait, a very wide action or more tighter wobble.

If its narrow and long, it will run deeper, square billed crankbaits are usally for shallower waters with a nice tight wobble action. The bills also helps in preventing snags, u can use the bait to bang it of structure on the bottom to produce reaction strikes.

Hope that helps somewhat, I'm still learning too.
