Underspins are one of the best ways to rig soft plastic swimming-style baits for northern pike. Whether you use swimbaits, curly tail grubs, ring worms or other baits, just make sure you’re rigging these with baits that have some type of swimming style action on them and you’ll get plenty of bites from northern pike. Use the lighter jigheads for fishing around the shallows and around weeds. Go heavier when fishing deeper water and you can connect with some big pike. Underspins are one of the better action baits for catching northern pike.
