I used to be on a kick that Dicropan was darker, but Oxpho blue lasted
longer, so I would put Dicropan on first and get it down in the micro
valleys, and then run Oxpho on the micro ridges.
That trick makes dark and long lasting cold blue, but it only works on
steels that take both cold blues well.
If you can find this stuff, get some, and you will broaden what you can
do besides Oxpho and Dicropan.
