Several controlled studies have been done by Doug Hannon, Berkley, and Glen Lau that concluded the plastic worm was the #1 bait that bass had the hardest time being conditioned to avoid.
Crankbaits, spinnerbaits, and action-tail jigs have an acoustic footprint (combined with other noises) that bass can easily recognize and be conditioned to avoid, Glen Lau even believed they could pass that trait down to their offspring.
In contrast, baits like a zara spook, fluke, stingray grub on a darter head, ect. (IOW baits that "slice through the water") were taken repeatedly more often by the same fish.
A struggling shiner on a hook below a balloon rig could probably condition some Florida bass, but I doubt it would prevent the same fish from eating a "free swimming" shiner that is NOT tied down and struggling.
With that thought in mind.....How long before resident NFOW trout stop chasing/biting those big streamers that have become the vogue thing to throw?
I've been noticing for quite awhile (when the water in the creeks are clear enough to easily see fish) that they are less spooked by a slowly idling outboard than they are a trolling motor. They will swim right along beside the boat when your idling along with the outboard, but they'll bolt when the trolling motor gets within 20 feet of them.
