I shoot 3 fingers under and have always anchored with my middle finger. For hunting situations this has been great. Problem is I get the crap kicked out of me at every 3D shoot. I didn't realize what an issue I was causing myself until I starting shooting a 50# Jerry Hill longbow. Much slower than my 60# Sovereign Ballistik recurve. I kept running out of gas before I got to targets that were in the 40 yard plus range. As a fix I worked on anchoring with my index finger and shot 40 yards most of the night. Tremendous difference. Has anyone else done something like this?
