Just to add to above (since it's not letting me edit). My GP3 (120) always game in black labelled boxes, in firecracker red paper that was nicely thick, easy to tear open and lined on the inside with foil. A+ packaging. Apart from the tape thing.
Never had blotches, spots, or other artefacts, except the time I tried pushing to 3200. Tonality was still good, weird pattern over it though.
My EI 800 semi-stand Rodinal 1:100 worked out great. Usually just shoot at 100 though.
Haven't shot anything in a while.. might order some new rolls.
