I noticed that 3 year old Polywarmtone Plus fiber lost contrast vs my last shipment of paper. At six years, maybe the continued darkening has something to do with fog or Zonal Pro, a very strong developer.
I don't know of a paper similar to Polywarmtone Plus. For me it was the separation of low to mid tones and the rich tonality when cooled in KRST. However, Ilford WT is a very nice paper which after tweaking negative development may provide results which are close enough. Oriental Warmtone has slightly higher low/midtone contrast than Ilford WT with my negatives. Ilford will print about a .5 higher zone vs Oriental WT.
If you switch paper developer to Ilford PQ or 130 you can avoid the olive color. Potassium Bromide is a factor for the olive color
