Strike Pro (who I am not sponsored by or affiliated with, blah, blah, blah), I must admit, comes up with some very clever lure designs. In the hardbait category, I would say that their Flex X is one of the most realistic baitfish imitations I've ever fished. Its snake-like action comes from multiple joints--a recurring feature on Strike Pro lures. Not too long ago, the company unveiled their Flex Crawfish, with a multi-joint tail that folds under as it swims, replaceable soft claws, a weedless hook, and unique eye in the middle of the back that makes it work when flipping, pitching, or jigging. It's cool, no doubt, but I can't help but wonder how important that level of realism is when it comes to mimicking a crawfish.
