Sorry once again I am a nazi I don't really care but lore wise a bow requires a certain draw weight now elves are stonger and faster than man so it would just make sense that their draw weight would be something ridiculous I don't really care just saying lol

Bow of the High Elves

A Bow of High Elves is the weapon used by High Elves of Lindon and Rivendell, the bows being amongst the best bows of all of Middle-earth, capable of shooting arrows at great distances. Elladan, son of Elrond, was reputed to use this bow to great effect. In the film rendition, the High Elven bows appear to be made of a golden metal, thus requiring great strength to use. 

From the wiki once again don't care not trying to be an asshole just proving my point.
