I used Maxima 85-150 5wt at 220cc inner and 300cc outer. It's 16.2 cSt@40C/4.4cSt@100C/VI 201. I've had this same oil in all the Showa and KYB forks I've run for years. I love the action of my 48 Zokes forks with this oil.
That said, cartridge and outer chamber fluid should be the same as the Zoke 48's are a semi-sealed cartridge fork.
My forks are good everywhere. Rocks, square edges, whoops, etc. If it helps, here is my compression stack:
