Yep colour balance is indeed a pain, i'm still stuck on film and my beat up but much loved Leica M2, I D&P my own too and colour printing filtration can be interesting too.
Personally I use two very old Mole-Richardson fresnels, have seen those fluorecent boxes though.
You'll be telling me you're still using VIR cable next!
Seriously though excellent gear you have there. I used to shoot film, but never really got into it that much, just 35mm SLR stuff. Snapshots mostly.
I used to help my dad sometimes develop his B/W stuff, including cut film from a Speed Graphic he had at one time.
Been toying with the idea for some time of getting a vintage MF film camera like a Mamiyaflex.
