well the thing with the bows.
first of all i wanted to suggest that building bows should be more complicated. in fact, it was as complicated to make a decent bow as a decent sword. bows were made out of special wood or even different kinds of wood. there are immense forces at work when shooting them, the wood had to withstand them. also they were very very umm howd you say? they decayed FAST

like the owner took damn care of them. any water - bang there goes your sinew
that said, if they get harder to make, they also need to get stronger

and they shouldnt need "string" ...
now to the bows.
long bows are of no use for hunting or one on one fights. theyre really big (like it was said before, sometimes even larger than its owner) and were used in wars to shoot at a large group of enemies, not to kill them, but to hurt them, at best make them unable to fight and to lower morality. basically you cant expect to hit anything you aim at, at that large range. i mean its hundrets of meters range...
but thereve also bee a lot of different bows, for example one that horsemen used, i dont know from what culture. the bow looked like this

the one is stretched the one not. you can imagine the power behind such a bow... those bows were mainly used by nomad horsemen. but also by others. i guess its a classic compound bow, but im not sure how its called in english.
so theres a nice variety =) cant write any further, gotta go
