Trying to push the thread back on topic I'd like to add that TMY in Pyrocat is my favorite for situations where light is limited. For what it is worth I agree the negatives look simply gorgeous on the light table and are easy to print. It certainly has very good midtone-separation even if the light is rather dull, the low reciprocity fauilure can be a *big* advantage under such conditions.
I haven't done much testing under bright light untill lately and haven't printed these negs yet. If TMY does nice under such conditons too it will become my standard in 120 as grain and sharpness are excellent at the enlargement factors I use (x6.5 beeing the max).
