Mark - I've been using 1:50 dilution of Rodinal, 10 min at 72 deg. Constant agitation for 30 sec, then two inversions each remaining 30 sec. I agree, VP is a fine film. Recently shot the Baltimore harbor in fog and got exquisite results. You will see more grain than Xtol (but you knew that anyway). Printing up to 11x14 grain is not a real problem for my work.(posted 8514 days ago)Good luck
