Jobo CPA2 or CPP or CPE2 rotatingmachine to take up 2820 testdrum(smallest tank).
2517 70mm reel (172cm film lenght), of course one can use multiple reels in 25xx-tanks but i dont want to risk more than one film...
It so easy loading the reel and using the machine with lift.
But maybe you are right doing fully manual. Power-failure could be catastrophic.
cutting down 70mm film after shooting is another option to avoid 70mm-developping. A manual cutting machine would be nice.
