Leave the split ring on the crank and attach the business end of the snap swivel to the split ring. I used only a duolock snap for years until a fellow CDC’r proved to me that the snap swivel does not change the catch rate whatsoever and nearly completely eliminates line twist when catfish or foul hooked yellow bass take down a lure in your spread. I use #7 eagle claw black barrel swivels with interlock snaps that have a more rounded swivel end to allow free motion of the lure.
