I would suggest hiring a charter for a couple trips per year and watch, listen and ask questions. Also braided line (no stretch) is very important for feeling the Wallete bite. Are you working the swing?

coevannacharters.com has a "Drift Fishing Tactics" page. Check it out. Captain Dave and his guys specialize in drift fishing. Nice guys as well and they will get you putting fish in the cooler.

Enjoy the lake
