Thanks CK. It took me a fair amount of looking to be sure I was seeing exactly what was going on there. Turns out your picture is just like your written description, so no actual surprises. It just took it a while for what the picture is showing to sink in. Good info & writeup.
This is the other thread, I’ll link back from over there: triple XP-L project, need your input. Problem solved?
I guess the time is coming for me to get some XP-L emitters.
