Barbed wedges?
Maybe what Kyle was referring to...if you plunge in about an inch or less below the center of your backcut, you can sink a wedge into that plunge cut, and one directly above it in the back-cut, and have the stacking effect without plastic on plastic. This works for three wedges, too.
