Slide the plug up the leader until it clears the hook. Then, spin the plug on the leader noting the position when it stops. Mark the topside of the plug carefully, as the hook point needs to be in alignment with this side of the plug. These are the plugs that seldom fish well, as they spin instead of swim. Natural is my favorite, for another reason.
Unfinished wood is very porous, it soaks up scent real well.
Hope these tips help.
