I've gelled strobes to get the ortho look w/ Tri-X, but if you don't like filters, I'm guessing you don't like a bunch of strobes with Gels. I've had some luck getting continuous tones out of Ortho Lith, but (because I'm fairly inexperienced) I'm not sure exactly how or why one negative will have mega high contrast and some will not, I use relatively similar dilutions of Rodinal pretty much in every batch.
