Gruesome Grubs These short shank Gruesome Grubs are a long forgotten secret. The small 1/8 oz tri model presentation paired with a small minnow or worm works excellent for targeting trout species, walleye and panfish. You can also pair these Gruesome Grubs with a leech in the spring for those finicky walleye bites. The added bonus of the short shank with no collar also means quicker hook set. Many fish species target grubs as a natural food source..... so why not use jigs that already mimic what fish eat?
