Saurons Weapon of Choice?

[Tuor in Gondolin]

And no, I don't count Saruman's cheap shot at Frodo with his fingernail clipper.

Well hobbits used appalling weapons also, the universally banned LSB umbrella
of doom, for one.

But the comment above about taking out Sauron long distance with arrows and spears puts another whole in PJs LoTR depictions. In the prequil (actually good overall) why not have those hundreds of elf and Dunedain archers (directed by Elrond) just pincushion Sauron. After all, in the movie he's a rather big target, hard to miss, and the archers were knocking orcs off the top of Mount Doom.
