Take what you're doing and go to Carters Lake. You can thank me later.
Exactly what I thought when reading this, and I doubt it's what Bear44 wants to hear.
I only fished Lanier a few times with guides and guide friends at the time. It was OK, but not like Carters. That's not to say you are going to load the boat at Carters. It can be tough.
Bear, I wish I could help. I don't remember locations are Lanier specific strategies. Just make sure you are using light line on that clear water.
