I didnt read it, and this is the last thing I am saying regarding my loosing argument, but I learned it in school. Not sure if the teacher knew what he was talking about looking back on it now?! I looked afterwards, and I did find that early native americans used bow weights from 15 to 30 pounds? That was before they started using sinew backing? But I am not sure if that website was credible?? So it is a mute point.
