glad it worked out, but as the others with more disc experience have stated, its probably always better to do stuff to the pads first, to see if thats the issue, rather than reducing thickness of rotors if you are a bull in a chinashop with sanding, and or doing uneven sanding.
My take on the article mentioned, is that my disc looked like the one in the photo, and I did really really minimal sanding, and was super conservative in how much I pressed etc.

but glad it worked out.

Still prudent to get a proper evaluation of rotor thickness though by anyone doing this, as I defer to those with lots of experience who brought it up.
