Not an expert but I know a bit about the area you fish. Summer is tough for me too. I am not sure what I would do if not for drop shot and c-rigged fish dr. Point ten would be great place for you about three casts from the sign. head up lake and look around that island some too.
Hopefully the experts will weigh in. I wouldn't ignore the shaky head either. Those two spots should get you bit year around.
