I have done some reading and figuring but I don't know If I am right. I need help choosing the right arrow. I have a 29'' draw length and 60lb draw weight. I know that I need a 30'' shaft, and I think I should probably go with 7 grains per pound. or should I go with six? So, if six, I would have a 360 grain arrow shaft. So what broadhead weight should I choose? This is harder than I thought. Help?
