Draw weights should be chosen to match the arrow spine they're shooting.
I will respectfully disagree.
I believe an archer should choose his poundage first before he chooses an arrow. But choosing that poundage should be done through testinga bow at various weight ranges. If you have your mind set on shooting a Mathews, shoot the 50-60lb model then try the 60-70lb model. Finally decide on the draw weight that fits you best....THEN get arrows that fit the draw weight. Thus nothing is done arbirarily.
If you pick an arrow first, it is like choosing a camo before you decide on where you are hunting. Makes very little sense.
