Great news that a new yet familiar film is coming out, but yikes!! 30 mins in Rodinal 1:50 would seem like it would practically irradiate the film. I never used APX400 as I had problems with it and so used other films, but APX100, that was a different story and I'd buy a bundle of that.. Not sure why ADOX made APX400 take priority over the APX100 film?? APX100 was 'THE' film... I'd down tools and switch in a heart beat for that film to come back.
