I've been using the FF (Famous Format) No.1 Monobath for about 5 months now. I absolutely love it. 6 minutes to develop, inversion-agitating every 30 sec., then 5 min tap water wash. Done. And all at "room temp" 72ºF!
At the end of the wash I stop the tap and swish a tiny little bit of dish soap into the water, dip and dunk the reels a few times, finger squeegee once or twice, and hang 'em up. The whole process, from loading to hanging takes about 15 min!
As (I hope) you can see, the results are very nice. Crisp, clean very little grain and nice contrast. Of course, that's the T-Max talking, but the monobath definitely "agrees" with it. It also works fine with PanF Pro 50. Next I'm going to try Ilford Delta 3200...
Only note is that you definitely have to inversion-agitate. I tried being lazy and spin-agitating on one roll, but that created a streaky negative. (Spin-agitating E6 works fine.)
