I have always worked with liquid developer. Years ago, I used Rodinal, but I changed to Tmax because I was looking a smaller grain. Later, I proved HC110 (1:47) following a friend recommendation. Since that time, I only develop with HC110 (1:47). I like the results that I get with Trix400, Tamx400 o Tmax100.
Additionally, it is very cheap as it last for ever. I recommend you to prove it.
