ok, so I know you all probably get tired of these questions, but I have one exposed roll of 35mm Efke IR820 and only one roll. The MDC isn't much help for HC110 since I mix mine at 1+63. The Rodinal suggestions are slightly more helpful, but they still don't tell me what the characteristics of the resulting negatives are. If any of you wonderful people have some experience with either of these two combinations, I would love to hear it! P.S. I used a dark red filter (didn't want to buy an IR filter just to try one roll) and bracketed exposures, if it makes any difference.
