I am going to be down there next weekend and prefishing this weekend for a tournament as well and have just been told basically what they are saying... Don't stay in one spot move and hit as many docks as possible... Throw top water in the morning and find docks that have something different than the majority of them to find the fish... The main thing is eliminate what type of dock and location isn't producing the large bite and change stuff around because supposedly you should be able to go down there and catch a lot of 3-5lb fish... When is your tournament?
