In my opinion they are not better than using real worms, but like burtess I too have caught steelhead on them. I hook them near the head maybe 1/2 inch from the top on a 3'' red one. If you hook them in the middle I don't think it looks as natural. They do work, but I always say nothing beats the real thing. I never had much luck at all on the little pink grub looking ones made by gulp I would use regular ol maggots over those any day.
