I went and built a miter board for my filet knife to get the 45/45 cut dead on. I also use a different hook technique that and old salt taought me. I thread both hooks through the lower (most rearward) part of the cut and wrap the most forward hook over the back and insert it just behinhd the dorsal fin on the side. Then I take the most rearwrd hook and wrap it back over and stick it in the herring just opposite of hte other hook. I end up with a herring wwith 2 hooks sticking out of either side in the same spot. The old salt (who fished for many years in Puget Sound and also guided in Alaska predominately mooching) swore that this was the best technique. I have noticed that the strike to hook up ratio was better.
