SS 2 3/8 sinker question

[Adam_777]

I'm talking about one of my favorite plugs of all time.Deadly out of the box used day and night.Super Strike 2 3/8 oz sinking popper.Black eyed gold.I am wondering if there's a way to add a rattle to this badboy without ruining the action.I'm not sure if they are hollow or solid.I have some plastic rattles I use for soft plastics.I was thinking match the size of the rattle to drill bit.Drill a spot in the plug the same depth as the rattle and finish it with some epoxy.Anyone ever tried adding some sound to one of these plugs?
