Last night I was shooting these back to back out of my quiver as I hadn't taken my broadheads off of my maximas from turkey hunting and I have lots of 400's so I would shoot one 400 and than a 350 and the 350 was much quieter. I thought that the smaller the number on an arrow the heavier the spine weight. Any way, the 400's create more noise than the 350's do upon release from my bow.
"Spine weight" is an inaccurate term as spine refers to the stiffness or a lack thereof in an arrow, the less spine the more " flex " in an narrow and vice versa, right?
