The more resistant to bending a bolt is, the more "spine" it is said to have, and a crossbow with higher draw weight ideally needs to be paired with a heavier bolt point and higher spine specifications. The weight of a shaft is usually in grains, and product descriptions may provide the total weight in grains, or in grains per inch (GPI), for ...
Dynamic spine is largely determined by shaft length, head weight, and static spine. Static spine is the stiffness of the center portion of the shaft under static conditions. [ 19 ] The Archery Trade Association (ATA) (formerly the Archery Manufacturers and Merchants Organization (AMO)) static spine test method hangs a 2-pound (0.91 kg) weight ...
ATA is defined as the initial velocity of a 350-grain (23-gram) arrow when shot from a bow with a peak draw weight of 70 ± 0.2 lbf (311.38 ± 0.89 N) and draw length of 30 ± 0.25 in (76.20 ± 0.64 cm). IBO speed is defined as the initial velocity of an arrow with a weight of 5 grains (0.32 g) per pound of draw weight.
Some modern recurve bows are equipped with a mechanical device, called a clicker, which produces a clicking sound when the archer reaches the correct draw length. , traditional English Longbow shooters step "into the bow", exerting force with both the bow arm and the string hand arm simultaneously, especially when using bows having draw weights ...

A direct comparison between a fast hand-drawn replica crossbow and a longbow shows a 6:10 rate of shooting [92] or a 4:9 rate within 30 seconds and comparable weapons.
