From what I have experienced, and watched on an underwater camera, the take is like a taste. Unlike summer swimming and gorging right on down to the gullet. With a still bait as in deadsticking, the bait most times goes in and out of mouth before commitment. The treble will catch on exit. How many times have you detected a bite while jigging and strike and nothing there. Its out of the mouth. Advantage camera, strike when in mouth.
