Hi! I got a bulk load of tri-x(never used it I used TMAX 100 and 400,plus x,agfa APX,neopan SS and Across etc). I use tetenal ultrafin liquid(1+20). What is the times you would use for such a combination and what is the optimal speed(some say 320 some say 400.Digital megatruth says 1+10 9 min for 400)
