What program dealing with Symphony sheet music do you consider to be the best?

I am writing a Symphony on a Yamaha synthesizer. The music is saved in the midi format. But I want printable sheet music. What program do you think is the best for that purpose? Sibelius 6 is fine but the harp scores are all wrong there. Thus, I want sheet music of my music peace to be printable, according to the music rules, so that the orchestra could play it.
