It is a fact that a higher brace height will make a bow more forgiving. The reason is because the arrow comes off the string quicker and any form impurity after that point is minimized. Speed bows get their speed from having short brace heights, because the longer the arrow is on the string, the more energy is tranferred to the arrow. During that time any torque, push, drop, or pull (to name a few) that a shooter may do affects the arrow flight. I am not saying that nobody can accuratly shoot a speed bow with a short brace height, because most experienced shooters can. However, as you shoot, you tire with any bow. As you tire your form breaks down and sometimes you don' t even know it. For example, It is why you start shooting right and you can' t figure out why. When you tire and your form fails in one area or another a longer brace height bow makes it matter less. Speed bows work fine for 3-d shooting because you are only shooting 30 or 40 arrows one at each target and you have a ten or fifteen minute break between shots. however, on a field round you shoot four consecutive shots at each target with a total of 112 shots in a round. Most shooters (not all) will experience a form of tiring in a field round. It really depends on the type of shooting you will be doing.
