I would guess that most traditional archers have never had a lesson from a "master." Whether you can reach your potential this way depends on how much of a natural athelete you are. Rick Welch, a "master," has never had lessons from anyone else. Dave McReynolds, "not a master," has had lessons from several masters which have improved my shooting immeasurably. When you're trying to teach yourself, you just have to be in touch with your body and see what works and what doesn't. The biggest problem most of us have is that we guess the wrong solution for a problem, and then we end up with two problems rather than one problem.
Most traditional archers use a bow quiver when hunting. It is quiet and the arrows are easily accessable without making much movement to get one. The problem is, most people don't practice with a bow quiver because it is not as convenient to use on the target range, and repeated withdrawals of arrows will eventually wear the arrow holders and they will become sloppy. If you don't practice with a bow quiver, your bow will definitely have a different balance when you put one on to hunt, and will take a while to get used to.
I have solved this problem by using an Arrowmaster quiver by Safari Tuff. It is very convenient on the target range, and is also easily accessable when hunting and quiet (if you stuff a sock in the top to keep the arrows from rattling around). Rod Jenkins, who owns this company, is also one of the "Masters" you might want to take a lesson from one of these days.
