first of all...

"Choosing arrows is a two-part process. First, decide what arrow weight you want to shoot, which in effect helps determine the type of shaft you'll need. Second, choose the correct shaft stiffness to complement your draw weight and arrow length.

Determining weight and speed goals:[/b]

Not every bowhunter needs to shoot the lightest and fastest arrows available. In fact, shooting feather-weights can damage your bow and accessories. Light arrows don't soak up as much of the bow's energy as do heavier ones, leaving more energy behind that has to be dissipated through vibration. If your arrows are too light, your bow can literally be shaken to pieces. The Archery Manufacturer's Organization (AMO) has proposed a standard minimum arrow weight of roughly six grains for each pound of your bow's maximum draw weight (60 pound bow = 360 grain arrow).

By today's standards, a heavy hunting arrow will weigh 8 to 10 grains per pound. And, if you really want to go for all-out speed, the standard of 5 grains per pound set forth by the International Bowhunter's Organization (IBO) for its sanctioned 3-D tournaments is as light as you dare go."

Does the above refer to a complete arrow (vanes, broadhead etc.) or just the bare shaft?

secondly i only have a 27" draw, 70# draw weight, and would like to compete with my hunting bow in the off-season, any suggestions?
