I first liked WT semi matt for it's creamy highlights in the WT developer. However after comparing Forte PWT in 1+9 with the Ilford paper, I prefer he browner dark tones of Forte's paper. I found that Ilford's paper was too neutral toned in the blacks for certain prints.
At the moment I am playing about with different dilutions of the Wt developer, but love the softness that Ilford's WT and CT developers offer. I think I'm back to 1+9 for my preferred dilution.
I'm fairly sure that I'm having to scrub my trays that bit harder to get them clean after using Ilfords WT developer also! I haven't made any comparisons with Agfa neutol WA just yet, but as Ilford's developer is easier to get hold of and cheap I'll stick with that.
