This has been a technique that I learned from the Cachuma king Howdy Bernth about 30 yrs go. His clients were not always the best fisherman and needed a easy technique to catch fish. His go to lure was the 5" double tail grub & skirt in smoke sparkle color and 3/8oz head. Simply throw it out and begin a very slow retrieve just over the bottom and wait for it to get the spongy rubber band feeling before setting the hook. It can be a very productive bait when the grass is up and rocky banks where wind is blowing bait up.
