Tommy Biffle uses them in his Biffle Bugs. I know this because when he was on Tawakoni with PAA (RIP) I got to be an observer with him and since that was all he was using pretty much, he almost ran out. I stopped at Bass Pro for him that evening and got him another bag. I'm sure he uses the Gene Larew ones now since they are his sponsor. He would not use them without one.
