I mix-up and use the original Wd2d pyro developer for my 35mm b/w images. I get beautiful grain free results on APX 100 and Tmax 100. The Wd2d developer, as originally published in Peterson Photographic (and available online) was designed for small negatives. Some of the other Pyro developers may be more intended for larger-format work. My negatives print well in the darkroom, and they scan very well also. For my particular work, I found that I had to increase the amounts of stock solution in making up the working solution to get the stain results I wanted.
Here is a link to a 35mm negative scan, of APX-100 developed in Wd2d.
