Let me say, with all due respect, that it would be extremely difficult to determine if one lure outproduces another. You'd need to catch a lot of fish, over a long period of time, under controlled conditions, to make that determination.
That's a lot different, of course, from having confidence in a lure.
I've been using crankbaits for 40+ years and have seen plenty of fish caught on modestly priced lures like Rapalas, Norman, Bombers, Mann's and many others.
I'd be first in line for the $20 baits if I thought they'd get me more and/or bigger fish, but that just doesn't compute for me. Maybe the expensive lures have better hooks, finishes that are works of art (more for our benefit than the fish's), but I just can't see them attracting more strikes when I see the action on the lures I mentioned.
