I believe he's refering to the Brads. I have heard of upriver guys doing it with loose skein eggs. Oil packed Tuna was far more popular and successful. If I had eggs and were fishing up there I would run them behind and sng etc. And use another bait like Tuna fot the Brads. You can put any scent producing agent you want in those things. I just can't forego the presentation of eggs by stuffing them into a plastic bait fish.
