As senko 77 said I dont think minor misshaping of the baits affects lure performance. Now if you have a bait like a swim bait or a craw with flapping claws and the appendages are misshapen then it affects the action and I would agree that I wouldnt use it. I have never had a problem with zoom baits and they are my #1 bait of choice. You just cant get a better bait for the price IMO.
