That confirms my “gut feelings” and I am all for those. It’s something like the switch from flat (which I detest so much) to PH. It was a major positive change. I guess in a few years from now I’ll be looking at PH heads with similar disgust as I do at flat cut heads today. P. S. - Gerrit - got the PCBs etched.
