Well, its a toss-up! Elijah is 5'6" and much younger than Frodo, who is about 3'6" and 50 years old! They're both pretty fast, though, but I think Elijah has a lot of reach on Frodo. He could land more punches that way. Frodo, being a hobbit, has an extraordinary talent of making himself disappear when the 'big' people are around; thus he might elude Elijah for awhile. Also, depending on the point in his career, Frodo has THE ONE RING, while Elijah has a prop! It is interesting to speculate, but I think Elijah would have to corner Frodo if he were to win this bout. If Frodo can keep moving, he could escape, but he doesn't want to match punches with the much taller and younger Elijah!
Sorry, folks! I couldn't resist!
Cheers!
