Tons of structure on your lake ! Don’t think of it being 50,000+ acres dissect it a creek arm at a time or spend time in one area until covered. Check the channel edges secondary and main also scan the flats . You will eventually figure it out. As already said fish the way you want and enjoy being out .I have caught tons of fish pulling and pushing but they ant nothing like feeling that thump to me . Or watch that cork twitch.
