An expert throwing a wobbler because someone doesn't practice what he himself preaches . Sure there's showmanship and editing camera trickery in the Dutchman's vid but as far as history goes its all supposition , its a tool , a means to an end , and before organized armies took up the idea the methods must have been a very individual thing . The quiver argument makes no sense at all , depends on intent and what's most convenient . Just my opinion , as I see it they may as well be arguing about who invented shoes .
