I can't remember what the weight of my arrows are, but they are what I was shooting when I was pulling 52#. I had my bow turned down to 45#. I have been reading about pull weight and arrow weight needing to work together. Does this make a big difference in the way my arrows fly? Speed? Spine? etc... Keep in mind, I am just shooting for fun right now, not competing. Just getting started again, but trying to learn as much as possible.
