While I agree with Bronto that the current balance of bows is fucking so assbackwards that it makes unborn infants cry in the prospect of having to live in a world with it, Bronto's numbers are just as stupid, and as to longbow being pierce, thats retarded.
In what world though is ANY bow going to have faster misile speed than longbow? I don't get it... longbow from yew would is natural laminate, and ask any historian who has stupied period just prior to and during 100 Years War will tell you, yew longbow is a laminate recurve bow, the arrows out of a 90-150 pound recurve laminate are going to be invisible to the naked eye for the first hundred metres, forget there being ANY bow faster.
As to crossbows too: before the steel arms, so every crossbow below Heavy Crossbow, needs misile drastically reduced: shit wasnt fast, before steel bows, crossbows were not even dangerous to men in maille.
