You can stick with the old adage of "bigger baits, bigger fish". In your Wednesday night league you don't want to go too big since you only have three hours, but if you throw something bigger you'll probably be eliminating some of the smaller fish but that's ok given the situation. If fish shallow, and you're dealing with heavily pressured fish go for the thickest cover you can find and try putting your bait places other people can't or just flat out won't.
