Line twist can be helped by continually checking your blades. Any number of things can knock them out of alignment. Work the lure next to the boat and watch it for twisting. Keep adjusting the blades until they spin with little or no friction. It's not easy because ajusting the blades will also affect the sound and water spray. It will take time, but there is a median where you get both the prop action without the twist. Good fishing.
(This lure when working correctly can actually get your rod busted. When grandma grabs it, the hooks can be straightened out as well as you end up just setting there with the rod butt in your hands). My best is a 9# Black Bass on a shad colored old style WS.
