I posted an image using this paper and the fotospeed lith developer a while ago in the critique gallery ( http://www.apug.org/site/main/album_...hp?pic_id=1268 )
Is not what I'd call gritty brown though. I only had a few sheets so didn't experiment much with it. The only technical data I can add was that the developer was 'room tmemperature' (probably somewhere near 20 centigrade)
hope it helps a little.
