Hey FryDog,
I've spent a little time on Rainy and a lot of time on Vermil. I've had much better success on V in the past and have caught some really big smallies up to 6#.
By Sept and Oct, the shallow wood/dock bite has cooled off and most of our smallies have moved out to rocks in the 10'-20' zone. Can be tough to track em down but when you do, its game on! Plenty of 3# - 4# fish to be had, especially on the East side.
