I don't do a lot of toning, only slight selenium to enhance d-max on exhibition prints. I have setled mainly on ADOX MCC 110 and Ilford Galerie , both grades 2 and 3 . The MCC seems to give the same deep blacks as Ilford MGIV with standard developers, but a slightly warmer tone. If you have negatives that don't require extremly soft or hard paper and you can do without split filter printing, nothing beats Ilford Galerie. Then of course you have the variations with different developers and toners, but that makes an endles amount of variations. Good luck with whatever you choose.
