I have moved away from Kodak and to Ilford also---the main reason is that Ilford is making a commitment to the B&W arts and as such I am going to use their products. Kodak does still make some nice stuff--but my move to Ilford was/is on my terms not being forced to move because Kodak stopped making something and now I need to find some replacement. As far as logical and rational I don't think there is a more logical and/or rational reason to make the move. As far as quality I have never found a difference between Kodak and Ilford, both top notch.
So good for you---you saw the light that is coming---the yellow father (as some have called Kodak) seams to be turning tail and running holding true to the yellow part
