But Kodak Porta 400 seems to be cheaper everywhere I look... And Fuji Pro 400H is just a few euros more for a propack.

I avoid Superia 400 these days since it doesn't handle underexposure well, I get magenta shifts fairly easily. Porta is superior here. But the colour palette of Superia can be nice tough. But I would never pay those prices for it.

Superia 800 in 120 would be cool tough. Nom nom. Or 1600 (it performs good when overexposed, a unique look). One can dream...

On a side note, wonder who is making the Lomo 800 120 films now when they switched from Ferrania stock? Porta 800 for that price seems too good to be true.
