I use the AGFA APX 100, 120 roll in combination with the German made TETENAL - NEOFIN BLUE. It's a one shot developer that makes per bottle 500 ml. working solution. It maintains a small grain and very high sharpness in detail, it also well balances the highlights and shadows. It's worth testing it. Check the TETENAL.COM site. I used Rodinal too but found NEOFIN much butter. Good luck ! Stavros(posted 8898 days ago)
