rmk, no doubt Stewart represents some of the finest available, but there must be a reason you might not consider DaLite High Power? millerwill of AVS was at the last GTG? He is a proponent of the material, and maybe you guys had a chance to talk about it, I dunno.
If you went for it, I would either move the rear row forward so perceived reflected light is not coming off the PJ itself, or move the PJ rearward if throw allows (most likely it will, especially going bigger), and last and most importantly, lowering the PJ some more.
VERY affordable screen, high ambient light rejection, no fear of dimness!!!! I just received my first free Mack bulb, and I feel kind of bad about taking out my present bulb at 850 hours, because I think it still looks great! And I know you know I have a huge screen.
