I agree, Ilford WT is an excellent paper. However, I have found Bergger to be more responsive to differences in paper developers and toners. I taught a class, Advanced Craft, at Pratt Institute, and every week I'd have the class mix two different paper developers and the students had to make prints in each one. In those days, Forte and Bergger were the most responsive. Ilford Warmtone less so. Regular Multigrade not at all. This included warmtone developers of every type, metol, no metol, glycin, pyrocat. And low and high contrast developers. They may be made in the same plant, but obviously from different formulas. It's a shame B&W printing paper has gotten so expensive. But if you can, make comparison prints.
