Duplicating film vs interpositive method for albumen prints?

[TimF]

Hi all,
I would like to try some albumen printing and am considering the best way to enlarge my negatives. The great thread in this forum advises making an interpositive then contact printing that to get the right size negative. However while researching the sheet film I'd need I saw that ultrafine have a direct copy film, so I could just do a direct enlargement to get a neg of the right size.
Can anyone tell me the pros/cons of the 2 options? Will it be harder to get the contrasty negative out of the direct copy film that I need for albumen printing?

Direct positive film is supposed to be pretty contrasty, so it could be good, if you don't lose too much detail in the process, and if you can get your zone VIII density to 1.6-1.8 or thereabouts. I don't know if you can develop it in pyro with good results, but that can give you more UV density, if you need it.
