To carry on with the four steps to perfect broadhead flight, quote €Make sure to re-check your arrow spine before you begin tuning. I constantly come across bow hunters who are using the wrong size shaft. Having an arrow that's too stiff or soft will make it impossible to achieve perfect broadhead flight. Make sure to consider all the variables that influence spine stiffness. According to Easton, the variables are shaft size (diameter and wall thickness), shaft length (about three quarters to one inch can significantly change shaft stiffness), weight of the broadhead to be shot (about twenty five 25 grains can significantly change shaft stiffness), draw weight of the bow (about two point five to five pounds can significantly change shaft stiffness), archer's draw length (certain shafts become significantly weaker when cut past twenty eight inches).

The string material (Dacron strings are slower and require a slightly softer arrow, for example), type of bow (recurve or compound with a wheel, soft-cam or speed-cam), finger or mechanical release (finger shooters require a slightly stiffer arrow), bow length (bows less than forty inches in length require a slightly stiffer shaft) and overdraw length, if used (three-inch-plus overdraws require a slightly stiffer arrow). If you shoot Easton shafts and have a computer, it's worth purchasing Easton's €Shaft Selector Plus€ program to help you select the right shaft. The program is much easier to use than a chart. Easton's website, http://www.eastonarchery.com, also has a free shaft selector, but it does not take as much information into account as the program. If you don't have a computer, check to see if your pro shop has the program.

If you have to use a chart, or shoot another make of arrow, be certain to read the instructions on shaft selection very carefully. Finally, keep in mind that your setup may vary enough to require a different size shaft than the one recommended. Good broadhead flight is almost impossible to obtain if you're not shooting a properly spined arrow. Read the instructions for shaft-selection charts carefully, and make sure to apply all the variables. Also, once you've got the right shaft, learn how to tune your own bow. Easton has a number of publications that will help you tune your bow properly. Now that you've got the right arrow, you need to tune the bow to the shaft. Note that I wrote, €You need to tune the bow.€ You don't have to be the brains behind the tuning, but you can't have your local archery shop do this for you€ end quote.
