I've had the luxury of working with a bunch of differnt negs in differnt soups on different scanners (howtek, scanmate, v750, 10000xl, imacon, 4990, tango).
Morrell/Nixon: tri-x + hc110
Bosworth: tri-x + d76
Gohlke: tri-x + xtol
Johnson: delta 3200 + xtol
Perrott: tri-x (@ 100) in xtol
vitone: hp5 + d76
Me: adox 25 + pmk; tmax + tmax; tmax + f76+; hp5 + xtol; fp4 + xtol; tri-x + pmk
They're all printable in the darkroom and, if you know what you're doing, can be scanned with good results.
