Purists will shriek at the Shimano Megarange, but at 72 years old, still doing big hills, I don't care. You will need a long cage RD for the 34t, but its worth it. First picture is as bought.
Lovely PR10! I covet in the extreme one of those small Mafac-mounted TA racks! I keep watching the 'bay for one to come up that isn't crazy expensive....
I can't say I won't end up there, but man are those Shimano Mega-range freewheels fUGLY!
