The best negatives I have made were with tray development and single sheets. I will qualify this statement by saying that I use a lot of Efke 25 film which comes pre-scratched at times. I also use PMK pyro a lot, so staining properties are important and evenly developed negatives are demanding consistency.
With a Yankee type daylight tank, I had problems with uneven skies and finally gave up on it. This may have been more due to my abilities and technique with PMK.
