Thought this might be a fun one. These two plugs below are my all time best plugs. The little one is a 7" AC Minnow. I've had to repaint it three times, it's caught that many fish. I would estimate conservatively that it has caught 150 fish for me including 14 in one day at Margarita one year.
The bigger one is my favorite 9" MS Slammer. This is the plug I caught my 15-12 out of San Pablo on as well as an 8.15 at spring lake in April of this year. It has accounted for probably around 50 fish so far.
