Keep in mind its not always how many different baits, but how you present it.....a stick bait/fluke can be flipped, dragged, hopped, jerked, wacky and even used as a topwater. If your budget is limited look for baits that can be versatile. The presentation is more important sometimes depending on the mood of the fish....if they're active they'll eat quickly once they've located your bait. If they're more neutral a slower presentation can entice them better sometimes.
The advice given has been good, but keep it simple. It's hard to go wrong with a zoom super fluke, most days this will catch you some fish, just remember to try different retrieves to get them to bite.
