I used the 7" finesse worm, color- pumpkinseed last year with good
success. Used like a 1/4" split shot varied the placement like from the
tip of the hook up 6" or so. I would throw it out and let it be while I
fish with another set-up. I had better luck with it than I did a senko
fishing the same manner. I would say because the tail would be off the
bottom just a bit wiggling with the water while the senko lay on the
bottom. In fact I just bought a specific reel (with clicker) to fish
just this way again this year.
One thing they will melt or deform a bit if left in hot sun inside a
car. Like was said already they last and last, well, unless you let them
get too hot.
