Not to be argumentative, but, if you have a bow that is out side of center and your wood clanks, it is more often than not, a sign of an over spined arrow. The nock end is hitting the bow as it passes. If it makes a longer sliding sound, you are risking getting a much under spited arrow shaft through your hand when the arrow breaks. On my one duo shooter I had that, 3/8" out from center, I had two options up the brace height or add point weight. I went to 190 grain Ribtecs from 160 grain Hills. The charts stated that I should have been 15 to 20 pounds lighter spine, took one test shot and the arrow cracked.
One other point, before an arrow is up to full speed and still connected to the bow string it is sliding on the bow, a noisy shaft will make a sound until it leaves the contact. No matter what the old wives tale claims, when a bow is outside of center, the arrow will bend into the bow, no matter if it is finger released or caliper mechanically released. It is simple physics, an object not in motion attempts to remain not in motion. The bend into the bow is a result of the bow string heading towards the center of the bow and the arrow attempting to remain not in motion. Try it with anything that bends. Mark it 90 degrees to a fixed object like a wall, Move the contact a couple inches over and then push it directly at the 90 degree mark. If you moved it to the left of center it will bend to the right. With some bows anything you can get to get the arrow closer to center and with minimal drag the better. With more center shot bows, I prefer something on the bow myself and sometimes I even build them out from center to match arrow spines.
