No matter how much you bring, there will always be lures you might wish you had with you. Take a couple of baits that have worked in the past, a couple you'd like to learn to fish better, a spinnerbait, a few worms, a jig or two and a few senkos. Everything should easily fit in a sling pack. You'll probably only be out for an hour or two, there's no need for 2 dozen of each plastic. 2 or 3 each of a few styles will be plenty. More than likely, if the fish are feeding, you'll do just fine. If what you brought doesn't get em' so what. Try again tomorrow. Have fun, don't worry about getting every fish in the lake. Don't put too much pressure on yourself to catch fish. Don't think about what other lures might work, concentrate of fishing the lures you brought.
