Luke, Fishinjunkie is correct. A cut plug with no flasher off the downrigger works just fine.
Last year we were up there in August and the fishing was fast and non stop.
My brother was fishing with a flasher, hoochie, and a herring strip and did real well. Late in the moring our bait supply was getting low and while I was searching in the bait cooler, I noticed an abundance of half filleted herring.
I ask my brother if he ever thought of using up a complete herring before he filleted another.
So I cut a fillet and got it to roll a litttle and still caught fish. They will hit cut plug bananas up there.
