Contrary to popular belief, long snell spinners outperform short snell spinners when working the mud. In this instance, long means anything from 5 to 10 feet in length. It's rare to find commercially produced spinner snells in this length, so you'll need to purchase components and tie your own. 10-pound Berkley XL is perfect for tying long spinner snells. In the past, Mille Lacs walleyes had in history of preferring florescent green and chartreuse, but with today's clearer water, metallic patterns get the nod.
Hooks are the next consideration.
Hooks, not hook, because you'll be running a night crawler harness. The distance between hooks varies according to night crawler size. In the event you decide to buy prefabricated spinner rigs versus constructing your own, look for models featuring quality hooks like Gamakatsu, Owner, Mustad, and Eagle Lazer. Trolling is the most effective way to get after mud flat walleyes. Firstly, trolling incorporates superior directional and speed control to drifting.
