I did only colour reduction (to 4 colours) and produced a 3.6 meg PDF
at the original resolution (down from 11 meg)

Can they be reduced to 2-color, or doesn't PDF support that?

I tried that, but it made the edges very harsh looking.
and didn't give much gain over 4 colour.

reducing the number of pixels by 75% got me only a 3% reduction in
size. (and it looked ugly when zoomed)

PDF lossless compression (deflate based) seems about as good as gif
(LZW based).

When I used 2 bit EPS files to produce the pdf I got the very close to
the same size as the sum of the gifs of the pages.

Can you post those PDFs please?

yeah, will do.
I've never posted such a large binary i'm just today
figuring out how to drive newspost.
