Also, a longer bow decreases finger pinch.

Bryon does a good job in his book. But don't get hung up on "the proper way" to shoot a bow. Traditional archery is supposed to be fun, not a job. Most people just anchor at the corner of their mouth, cant their bow until the nock is under their master eye, look down the arrow and shoot. The way I learned to shoot a recurve bow 38 years ago, is not the proper way now. And I am not going to tell you my technique. On the other hand, I can and do hit running rabbits, spuirrels in trees, walking deer and running hogs (I am 2 for 2, both good hits and both recovered within 40 yards). All I am trying to say is, just because your shooting technique is not what is descripted as the proper way to shoot a bow, does not make you wrong. The main thing is lots of practice, stump shooting and having fun.

Stump shooting is taking a couple dozen arrows and a dozen flu-flu's and walking through the woods. Pick out a pine cone, piece of dirt or low leaf (try to have a back stop, such as a hill side or stump) and shoot an arrow at it (field points, blunts or points with wire fingers work best). You will be surprised how fast you start zeroing in on the target. If you miss, big deal. Traditional archery is about having fun, not scores. Try again. And take someone with you. It's a lot more fun with two people stump shooting.
