wherever my Rohirims are, and Eomer, my heart is too, it doesn't matter if they're in Rohan or Gondor :)
I understand what you mean. This could be a tough question.
Riders of Rohan just rolls off the tongue ;) Plus it's not every day you see Bones on a horse, so I'll go for that. Then again, Gondor has the best loony leader, so that must count for something ;)
But that loony leader of Gondor has two handsome and heroic sons. They get my vote. I will give you and Dezz that Rohan is impressive, but Gondor will break your heart.
