My mom is wanting to start bowhunting next year(ya i cant believe it either lol) and we were needing a little help with what her arrow weight should be. I was thinking around 430-450 grains but i asked this question over on AT and they said to go light, like around 330 grains or so. She will be drawing 40lbs and a 23.5in draw length with a Diamond Razor Edge. So how heavy do you guys think her arrows should be? Thoughts?
