Developing Macos Cube 400c / Rollei R3

[capitalK]

I found some outdated Macos Cube 400c at a local shop and bought a few rolls. The developer in the darkroom that I use to develop is Ilfosol S, but the store where I bought the film does have the proper developer from Macos.

What will I gain by using the Macos developer. They have the regular and the fine-grain. Has anyone tried this film in Ilfosol? I don't necessarily want to buy the specialized developer if I'm only developing a few rolls.

Thanks in advance.

Bump for the European crowd who might have more experience?

Cube 400C and R3 are different on polyester layer. R3 is on clear polyester layer with double non-curling layer. Cube 400C is blue polyester and is missing the non-curling layer and is curling pretty much.
Both are TSF (traffic surveillance films) extended red sensitivity till 700nm.
You need a depth developer like RHS/AM74 or RLS/CG512.
iso 400-1000 RHS 1+7 or 1+9 is giving the best result. Iso 50-200 RLS/CG512 1+4 (on 24 degrees C !!). Do not forget a pre-soak for at least 2-3 minutes which is important for this film.

Here an example of R3 in RHS/AM74 (the original is comming from Amaloco Photochemicals, Ommen , the Netherlands)

RHS/AM74 1+9 16:30 min, 20 degrees C on iso 400.

So you'd recommend using the proper developer over Ilfosol S?

Thanks.
