Do yall think that salt is used as a scent as well as an additive used to attrack bass?

I don't think salt does much for a scent, altough probably helps with taste.

I agree with Will, salt appeals more to the sense of taste rather than smell.

As a result, salt is believed to lengthen the time that a bass holds onto a soft plastic,

because it mimics a living organism which all have high salt content. A less debatable fact

is that salt added to soft plastics will increase their descent rate, so the more salt added

the faster it falls.

The salt is used to give the plastic bait it's action on the fall.  The taste is a big bonus, cause they will hold on longer.
