I would say that I actually had/have a mild case of target panic. My groups have always been consistent, but getting the arrows into the X has been a problem. That being said, they have always been more than adequate for hunting purposes.
About a month ago I started practicing with a pure backtension release (TruBall Ultra Sweet Spot 3). This has really forced me to concentrate on my aiming. After 4 weeks or so, the target panic seems to be dying off, my groups are getting much closer to the X and I no longer tense up at the shot. This has correlated to much better overall accuracy with my wrist/hunting release.
That being said, I think the Lobotomy kit might also work, but then again I really don' t have much gray matter to spare.
