I’ve rigged them for Bass using a 3-way set-up. Impale the hook through the seam of the 3rd or 4th segment in the tail. Bring the hook towards the body section then exposing the hook in the seam between the body and first tail section.
It works well for Bass, I see no reason why it wouldn’t work for Walleyes.
Be careful though, some of those crawfish are illegal to transport.
