I have a queston,maybe you guys can help me? My wife shoots a 24" arrow at 43# her arrow weight is 355 gr. The arrows are ACCs 3-18/560 with a 100gr tip.I was going to change her to a lighter arrow, but will I be giving up too much KE.She hunts deer with me and tookher first buck this year.Her bow is a hoyt V-tek.Thank you.
