This is just my exprience when i started 14 yrs. ago. I think each person is different, as far as ways to shoot instinctive. The most important part of shooting this way for me was, concentration. If you concentrate on a tiny spot of an object that you are shooting at, and not just at the whole object, you will be successful. I shoot a floating anchor. I tried anchoring the same everytime, and just couldn't get to where it felt natural. But, the one thing that everyone HAS to do to be good, in my opinion, is high level of concentration. I think this is the most important factor of shooting instinctive. Not everyone can shoot the same. They always told me that, "shooting a stick, is like throwing a baseball to someone". Your instinct, and eyes, tell your arm how hard to throw the ball to get it there. Some throw underhanded, sidearm, over the shoulder, etc.. Its all how hard you concentrate, not the technique you do it with. Shoot the way you are comfortable with, and just concentrate on a spot, inside a spot. I would start out with a 30# bow, myself. Good luck to you. Just my opinion.
