I had two tremendous hits this morning without a hook set while drifting a creek on my local lake. I was second guessing my set-up and my mind slipped back to past posts about Kahles vs. circle hooks!! LOL!! When I reeled in to check the bait on one drift rig I noticed the cork had been squashed on the top and bottom, like someone with no teeth had bitten it. LOL! I checked the other rod that was hit and sure enough the cork there too had been hit. The catfish bit down with some force on both corks. I guess he was reacting to movement near the scent of the bait and hit the cork. Anyone ever noticed this on the drift rigs?? I have never paid attention before, but I will start looking at some of the corks from now on when I "think" I have a short bite.
