Nigel,
I have been using Neopan Across for years... I guess I have always been a huge fan of the Fuji brand due to the colour emulsions results. Also, Kodak and Ilford in UK seemed to be a more expensive choice to me.
Neopan normally gives me very contrasty negs with Rodinal, either normal or stand development especially in sunlight (not sure if it's the way I' developing...). As my taste changed through the years I wish I'd tried some other brands in order to get a less contrasty negative.
