Nice shootin'! Your videos are done nicely also. I recently bought a used Bama Hunter that is around 47 at my draw length. That is 4 or 5 pounds less than I've been shooting, and I agree with you about improved shooting.
I'm finding myself shooting much more deliberately, as in hitting my anchor and holding it there a bit til it feels right to release. It seems that fighting the draw weight results in more fliers since I tend to release sooner, ready or not.
My accuracy has improved, and more importantly, my confidence. My elbow is happier too!
Good Luck Hunting!
