I would also have to say Sam. I don't think Aragorn would take it, because he knows what happened to Isildur, and he doesn't want to fall to the same fate. No offense to anyone, I can't see Legolas ever bearing the Ring. Yes, he is an elf, but I'm sure that even elves have their problems, and I doubt that Legolas has a will strong enough to resist the Ring. Just because he's the son of Thranduil doesn't mean he's special. He's just another elf. The Fellowship woudn't let Boromir hae it because he expressed his desire for the Ring in the Council of Elrond, and at least Aragorn and Gandalf would be wary about Boromir. Gandalf wouldn't take the Ring, because he has already refused it, Gimli might have the will to refuse the Ring's power, but he's just another dwarf, and I doubt that certain people would let him have it. Merry and Pippin, I don't know about. They are hobbits, and hobbits are the people that are best for this task. Personally, I think that they would head for home, because the only reason they are in the Fellowship is because they were following Frodo. I think that Sam is the only other choice for Ringbearer, because thought he does posess it in Mordor, he is able to resist it (mostly) and return it to Frodo. So my first choice is Sam, and Gimli is my second choice.

NOTE: I was going to post this yesterday or the day before, but my dad kicked me off the computer, and I was unable to finish my post. Now, I can see that I can completely agree with Brinniel.
