I agree with Chuck. I have made many tests when the sunfish were biting on every cast using small segments of nightcrawlers. When I switched to artificials the bite slowed or stopped. I have tried most of the popular small lures. The only time I would recommend artificial baits, including Gulp, is when worms of some type are not available.
The only bait that will beat worms is crickets.
