Thanks for the comment. Yes, I use and LPL enlarger with the universal carrier and some A-N glass on top and plain glass below. Never had any real problems with dust, despite having a wood burning stove 20' feet away from my part time darkroom, although I put this partly down to using a Hi-Fi anti-static gone every time I load up. Nor any problems with odd reflections from the textured glass, even at 16x12 sized enlargements.
Love the camera and the format. Now all I want is a nice 6x6 to go with it and I can ditch the Nikon!
