A few things

[narfforc]

Well sixteen elves never had the rings, seven went to the dwarves and were virtually useless, and nine went to men, and he had them under control in the end anyway. If those sixteen had been given to elves then there would be no Nazgul, and I doubt very seriously that elves would have sucumbed to the effects of the rings as quickly as men. This brings us to which elves would Sauron give the rings to, name sixteen elves of major importance in The Second Age of Middle-earth that could do any damage to the Last Alliance, Sauron thought of only his own desires in the real world and could/would not have understood the elven leaders desires, I think that even if the Three had not been made, then any ring given to Galadriel, Cirdan, Elrond, Celebrimbor or Gil-galad would have been sussed, I cannot see the elves being duped so easily, this would then only nine.
