Ok, but why is it better? The Jo-Jan is all metal, very simple, and you can do 6 arrows (one fletch at a time) at once, then either 3 or 4 fletches per arrow by turning a knob until it clicks into place. As long as the nock does not move while doing the arrows they are perfectly spaced. So, I take it, being made of metal is the advantage? Anything else? Just curious by the way!
Thanks
