My thoughts are:

First off, ask around and find someone that knows something about the lake if possible. Local baitshops have been a good source for me. Brush piles? Hopefully Jerry Blake has fished there before and can offer some up :D. As far a jigs vs minnows, I like to fish minnows myself, but I am not considered a "seasoned" veteran like most. I have been on Cane Creek and did pretty good on minnows and jig fishermen didn't do so hot. On the other hand, I have been severly "destroyed" by jig fishermen. :D. Since I have built my "bobberwatcher2000 super special rod holders" (patent pending), I have found that is a good way to cover some water in 30 ' swipes. Good luck to you
