any worm labeled as finesse should work, those never get salted either
I never heard that so I googled finesse worm salt and found this right away
Compared to traditional soft plastic lures, Strike King®'s revolutionary Super Finesse Worms are softer, more flexible, have loads more action and are much more durable. Made out of a proprietary Elaztech material that offers a distinct floating advantage, Super Finesse Worms are salt-impregnated to add even more temptation.
The Strike King Super Finesse Worms are by far the best worms to use on a Shaky Head Jig!
