JJ seems like I have read something in the past that refects what you said. IIRC the reason they are called bolts rather than arrows is because they were made of metal in the begining to pentrate armor. That would certainly take care of the weight problem wouldn't it. On a side note I saw some crossbows in Italy in san marino that were huge they were 6 six feet long. They used them to shoot out slots in the wall just like the small cannon they had at the time. tom
