Comments:  One of the joys of being retired is doing the deja vu thing!   So after 30 years,  and discovering Freestyle again sells 127 film, I got me a Yashica 44 LM TLR and  have exposed 4 rolls of the Macophot U100 film standardizing my developer and  times.   All  films are developed in 450cc SS tank and reels, with 1/2" x 2 1/2" PVC pipe  spacer on the bottom to get film up into the soup.  Again, I will use total  QUANTITY of developer, verses the more common ratio.   3 minute presoak (water).  Each developer gives different results.   The Rodinal gives good grain, very good sharpness, but zone 7 or higher highlights tend to block in a long scale scene.   The Pyro negs have everything  there!

Printing:   Both developer negs will go to 7 x 7  inch enlargements without any problem.   Pushed to 10x10, the Pyro negs might  hold the grain in a cloud scene depending on how far back you are from the  finished print.   Stick with 7x7 for the Rodinal neg.   If there is no cloud or  sky in the neg, 10x10 inch looks very good from either neg type.
