I had a (now deceased) cousin that shot older compounds (with fingers) instinctive and was a true dead-eye. He was a gifted shooter with bows or guns. He was hell on game and could also shoot 560s out of 600 indoors. He was also tops on walk thru courses. I witnessed him shoot robin hoods more than once.
I have another cousin that shoots traditional with a release. I guess he developed pretty bad target panic and shooting with a release cured his problem.
I shoot traditional instinctive. And yes I said instinctive. I struggled with all sorts of aiming methods until I realized that when I hit full draw, I was on target and I needed to truly believe that I was on target. If I draw and concentrate on only my form (and forget about the arrow) then I shoot much better that if I try to fine tune my aim. In fact I really need to put the spot I want to hit in my subconscious. I know they say to really concentrate on the spot and I do...before and during the draw. But once I hit my anchor, everything but my form becomes secondary.
When I trust myself, it's like I'm not even aiming. When I consciously try to aim, I don't shoot as well.
