I fish a lake in Michigan with about 6 or 7 feet of visibility and weeds. The main forage is small minnows and bluegills with no shad in the lake. I throw a 1/8 oz. white spinnerbait and they have been slamming it. Could I upgrade to a white 1/4 or 3/8 oz. for bigger fish or would that not work because there are not shad in the lake.
