Has anyone used this? If yes what did you use? And was it better than regular rubber?

I have had great success with them in the freshwater, I am gonna try em in the salt this year.

Just dont leave em on the hook when your done or they will dry out like pork rind and dont leave the package in the sun or you will have nothing but a big stinking blob in the bag.

I have used gulp as a replacement for seaworms on a tube and worm with some success; not as good as the real deal IMHO but a good backup.
