Quick question, easy answerI hope. Im strongly thinkign about switching to carbon or carbon/alum. arrows this year wether or not I buy a new bow. Im drawing around 60lbs or so and was told id need at least a 400gr arrow. thats the easy part. Now is that 400gr without the 100 gr broadhead or with the 100gr broad head. I know carbons work by spine and lord knowsI dont want to be under or overspined. I wouldthink its 400gr arrow with a 100gr head making a total of 500gr give or take a couple. Would that be right?
