Have you ever notice that on some days, every bite with a circle hook leads to a lost fish? And yet, on other days, it seems everything sticks? At least fore me, it was proven it was the way I was tying the circle hook. Years ago, with a "Guide", I lost--or never hooked, every single Tarpon I was fishing for. Every one. Later, I looked at his snell, and saw he had it backwards. YOU MUST GO IN, through the eye, on the BARB SIDE. Think of the line as a straight pin, think about it. As the line pulls tight, it acts just like a hard, pin, either opening up the hook, or closing it tight. It matters, big time. Next time out with the circle was for Yellowtail, here in SOCAL. Not one fish lost, not one. And not one time, did a bite not lead to a hooked fish, not once. They say the problem with circle hooks is the large percentage of fish not hooked, I think that has a lot to do with how you tie the snell.
