So I am new at archery. I have a older compound bow and I went and purchased some new arrows for it. I bought gold tip XT hunters. The person helping size the arrows left me with zero confidence that they are the correct weight. Can someone advise what the proper arrow weight would be for a person pulling a 30" draw, 60#? I guess I also need to know if the XT hunters I bought are the correct ones. I found the spline deflection for my draw length and weight is .330-.370". Can you tell me a little about this?
