I have had similar experiences to Bruce in limited trials. ALL prepared baits that I have ever tried are inferior to actual worms, nightcrawlers, and mealworms (even stinkbaits on catfish - but stinkbaits ARE much more selective than natural baits and hence better at targetting ONLY catfish, IME). The Food Source Lures have worked about the same as various Berkley Gulp/Powerbait for me so far.
Trials by good bass fishermen who really know how to work a rubber worm would be very interesting. I am no good at that.
