I have been playing with my ACS CX 49# @28" and I have found that a beman ics hunter .500 spine cut to 29" with 260.00 up front fly pretty good and a beman ics .400 31.5 " with same weight up front fly good as well one comes out to like 525 grains and the .400 comes to 575 I was wondering if there is any advantage to shooting the longer arrow. I am loking for an arrow for hunting and I have heard a longer arrow will correct it self quicker making it more accurate I just wanted to here some input thanks.
