When it came down to the wire, I ended up swallowing the freight charge and buying some RO9 (Rodinal) from Vanbar. But, having used HC-110 when it first came out in Aus in the 1970s I will get some LC 29 and enjoy a mild flirtation with it.
In recent years I primarily used Diafine which I love. I still have one unopened package that I can mix and use but, with reduced space, I am thinking something that does not require two 3.8 litre bottle might present a welcome level of convenience. I've already been out to Punchbowl and purchased 10 litres of lovely distilled water.
