I'm not 100 percent percent sure what they're looking for, but in my best estimate, those irregularities in tracking on a straight retrieve, or following a deflection off of cover, seem to be the moments the baits are "hunting" before returning to a normal cadence. The theory is that this irregularity creates reaction strikes that otherwise would not have occurred. But why you'd need to fish 100 brand-name baits to find a "hunter" I have no idea. I don't see why de-tuning a bait with pliers, taking a Dremel tool to the bill or body, or adding sticky weights to the belly wouldn't turn any out-of-the-box crank into a "hunter." Maybe I'll just try banging my crankbaits off the rocks a bunch of times. Do you put stock in "hunters?"
