I have Gulp in worms and minnow shapes for trolling and jigging. There are times where they will catch fish, but nothing like live bait. There are ways to catch 3 limits using only 1 doz crawlers but I find it a PIA and just use as many crawlers as it takes. There are ways to keep the dirt problem down to almost nothing. If you don't want to use harnesses, alot of guys troll spoons and or cranksbaits all season and do quite well. When the floating weeds become a problem is when I switch to spoons.
