[LargeFormat] lightweight 300mm enlarging/copy/repro lens?

[Michael Sullivan]

Dear List,

I'm in need of a lightweight enlarging/copy/repro lens in the 300m 
length.
I currently own a Rodenstock Rodagon 300mm, but it is one heavy beast!!
In comparison,  my Apo-Nikkor 360mm weighs but a fraction.
The ideal lens would be optimally used at 3:1 copying artwork.

Any recommendations?
