An arrow with too much dynamic spine for the bow will not flex and as the string comes closer to the bow stave, the arrow will be forced off to the side. Too little dynamic spine will result in the arrow deforming too much and being propelled off to the other side of the target. In extreme cases, the arrow may break before it can accelerate ...
Modern compound bows are typically equipped with substantially stiffer arrows than an equivalent draw-length and draw-weight recurve bow would be. Another advantage of the center-shot riser is that the arrow need not bend around the riser (nearly as much or at all) during the shot. Fine-tuning may be accomplished by adjustment of the arrow rest ...

A compound bow is fitted with a special type of arrow rest, known as a launcher, and the arrow is usually loaded with the cock feather/vane pointed ...
Rootes Arrow was the manufacturer's name for a range of cars produced under several badge-engineered marques by the Rootes Group (later Chrysler Europe) from 1966 to 1979 in Europe, and continuing on until 2005 in Iran. It is amongst the last Rootes designs, developed with no influence from future owner Chrysler.
Arrow Dynamics' forerunner, Arrow Development, was founded in 1946 when Ed Morgan, Karl Bacon, Bill Hardiman, and Angus "Andy" Anderson, started a machine shop in Mountain View, California.
