Mytol
I use Instant Mytol 1:1, mixed up just before developing. I also aim for 21 degrees (on my thermometer, which I think is Jobo-branded, so probably decently accurate). I also have a habit of not using a meter. And, in this instance, I took a guess (based on the current version of FP4+, by my FP4 expired in 1987) as to how long I should develop. I sometimes try to stick to some kind of strict methodology. Sometimes.
I look forward to seeing your result!
