thanks all -
have emailed both fotoimpex and mpex (similar names huh)
we'll see - I'm pretty keen for the Efke as the price is good, that being said for whatever reason my FP4 negs come out better for Pd in side by side comparisons in all developers I have used, seems like with and adequately long time in the soup it just gives up and goes 'oh, ok then have a damn fine neg then' - others always persist in being comparably thin in detail and/or high base fog.
I'm not as scientific with as I know some here are - certainly more than my mates: "fb+f" WTF ?!? - heh heh, perhaps the extra expense of ULF will get me into it a bit more
