Jeff,for me,it was combination of the thumb knuckle under the ear lobe and nose to the feather that put it all together.I've had target panic problems in the past and that combination really just cured it.One thing is that the the anchor point is a little farther back which helps with proper alignment and helps me to attain and keep back tension throughout the shot.I've been shooting better than I ever have.I got the idea from watching Rick Welch dvd's.If you haven't seen the "Accuracy Factory",I would highly recommend it.
