    Default arrow spine

    I have 30 1/4 400 Fatboys. With 125gr tips and inserts(not sure what they weigh) with 3 fussion vanes with 14gr bushing and 9 gr nocks. Do I have to do anything to these arrows to shoot from a 30"DL 60lb Apex? And what do you think the total weight of the arrows would be? and speed?

    Thanks

    Weak but tuneable. From where you are you might need to turn the weight a turn a or two, but these arrows will definately tune. You could also shorten them a tad. Speed around 270 ish.
