I like the warm tone of the Ilford WT, but I would prefer a cooler/whiter base too. I have not tried using the Harman Warmtone developer yet with the regular MGFBIV. Sounds like a small project for this evening. I wonder if there are other papers I should try for that look.
I also find that the Ilford WT has very little if almost no tone change in Kodak Rapid Selenium 1:20 up to 6 minutes. Will try 1:10.
