For big direct contact overlays, have you ever had the acrylic bow out in the front? This is about 45 x 62, with Optium, over the print, over two layers of thick batting, over Di-Bond, over artcare foam core. I could remove the points and do it again with less pressure. It can be squished down so there's about 1/2" of space between f.c. and the back of the frame in back, but I gave it room to breathe, so there's only 1/4" of space. Even so, the acrylic wants to bow in front. I've sent Jim a note, but am also asking here. Have you ever done a big acrylic/batting overlay and had it bow out in front some from the pressure? Is a bit of bowing ever acceptable?
