Both the sword and the cloak would be AWESOME!!!! However, I have really very little use for a sword, despite it's nearly incomparable awesomeness. Being a city dweller nowadays, I'd have little use for the cloak, although I suppose it is really the apple of my eye. The rope though--now that I would adore, and use! I just purchased a house, and have recently spent some time working up on the roof. A bit of elvish rope would've been a comfort up there, let me tell you! Thus I have chosen the rope, with deep regrets that I cannot also choose the cloak and the sword.
It would look pretty and my electricity bills would go down if I could use it to light my apartment.
I thought about having the Mirror (Galadriel's mirror, not the tablod) but I'm not sure I'd have the wisdom to not have my head messed up from looking at it.
