All of my sticks are poured without salt. There really isn't much of a fall rate at all, especially if there is any breeze. The bait will just sit on top. I mainly pour without salt because the color is much better. These sticks are rigged Carolina, giggy head, Texas, split shot, etc. They will also stand straight off the bottom.
Alot of people fish deeper water with a bullet weight. If you are fishing them with a bullet weight, why would you need a salted bait?
