If I were you I would stick to what the xbow came with untill you become proficient. I have been shooting xbows for 10 years??? and still have not swtiched over. I am more concerned about minute of death rather than minute of angle accuracy. That doesn't mean that aluninum isn't really accurate at all but I think awshucks has done a bit of research. PM him. I think that you should experiment with different shafts as well as tip weight. I do not have a stinking clue about moon nocks. Ask The Squirrel.
