just wonderin if anyone had any tips for fishin for largemouth on lake hartwell

i fished there last Sept. for my regional tourny. placed 11th. we ran up to the river almost to Clemson(bout 5-10 miles away) fished coves with creek channels. Mainly we targeted barely visible brush pile and threw shakey heads( it took quite a while for them too bite sometimes, but they're there) aslo threw shallow cranks and spinnerbaits around piles and creek channel. **the winner got lucky passing by someone who was killin em off some dock with a spinnerbait, the guy caught his limit and told them they could have it.. they culled every fish they had at that one dock. >
