Thanks guys. My wife is shooting a Horizon Ranger XL at 24 1/2" draw length and 36# draw weight. It is 32 1/4" A to A and 6 1/4" brace height with medium/hard twin cams. She is using a caliper release on a string loop and has 1 tie on nock point and peep without tubing secured with two tie on nocks. Her arrows now are just what I could pick up at a bargin (ACC 3-28 24" long, 3 4" vanes, 100gr. field tips. I think they weigh in at about 320 grains total but will have to weigh them. When I Chronoed it it shot 182 fps. I am not a speed freak but want to give her all the help I can. The local shop is small and limited on what they have available to try.
