Jim & Eric:

I've had no streaking and/or non-uniformity of development problems with Pyrocat-HD and TP. I have heard of development uniformity problems with PMK, but have no direct experience.

I have stand, semi-stand and minimum agitation developed TP in Pyrocat-HD and have had very uniform results in all cases. However, personally, I find few subjects where I prefer the TP result over the results I obtain on the same subject with Efke 25 semi-stand developed in Pyrocat-HD.

When I am doing comparative testing, I usually use my Hassleblad (or my Hasslebladsky) and several backs loaded with different emulsions.
