Thanks all! Having shot a substitute subject (even though in December light - it was in mid day light-high contrast) on FP4+ and HP5+and Foma 200 I think that I will go with the HP5+. I'm intending to use my Speed Graphic (instead of my monorail, for the implied visual "effect" to the expected onlookers). The depth of field is a definite consideration. I hope that things work out the way that I intend.
