I have been using split baths of about 12 years and absolutely love them. Divided D76 is an extremely fine grain developer that is generally same speed where as Diafine is a fine grain but high accutance which tends to be a beautiful addition to your darkroom. As stated, you really cannot over develop and when you go to print your negs, you will find a small amount of work you will need to do... key word there is SMALL! You can make DD76 from scratch or buy it in kits (I have a recipe if your interested) and they both can be used over and over and over! To anwser your question about comparasions, I haven't seen one but I haven't looked either. Cheers(posted 8674 days ago)
