Iíve been mixing from raw chemicals for so long now, I would never go back to pre-mixed packets. The control one has, sort of creeps up on you. Plus if stored correctly, shelf life is indefinite; Iím currently using a bottle of Kodak Bromide with a use before 1964 date.

Ansco 135, D72, D76, FX4, FX5B are mostly what Iím currently using; with D76 and Ansco 135 my current go to combination.
