I appreciate all the help guys give on this but I truly think we OVERthink this stuff. It is a psychological FACT that you can only concentrate on ONE thing at a time. If you are thinking about all this stuff there is NO WAY you can concentrate on the spot you want to hit.
I have been shooting trad for almost 25 years too. I went to it as one who played sports and was quite familiar with being a quarterback and basketball player. I never took a basketball shot in my life during a game where I had to "think" about the position of my body etc. You work through those things in practice, step by step. But when it comes time to shoot- you just shoot. I have never had a problem bending at waist, thinking about form, etc etc. . . The arrow goes where I am looking-PERIOD!
The only problem is focusing on a spot. I have learned to use the "button technique" as described by Jay Kidwell in his book. That has made a HUGE difference for me. If I do not use this I would tend to shoot high or over the back as my mind would focus on the entire shoulder. And there is no practice I could do to that would stop this on an actual deer! (Its called "stimulus confusion"-its a brain issue that physical-form practice at targets will not alleviate. . . the Button technique is designed for people that have this conflict- like ME!)
Love all the Tradgang input- but be careful you do not try to over think this thing- it is suppose to be natural and fun. Take certain days to practice certain aspects of your shot- but when it is time to shoot your deer (or target). Pick the button and hit it- PERIOD!
Good hunting and shooting.
