I'm about to buy a Vutec screen and I'm on the fence whether or not to get their curved, 3D-P model.
It will be 100" diagonal 2.35:1 AR using an anamorphic lens.
Like the original poster, I am interested in knowing what the consensus is among this group about screen curvature in home cinemas. Masking would be nice but I don't think I can afford it. Throw distance will be pretty close, probably 15' or 16'. Speakers will be flanking on on the bottom edge at center. The room has angled walls (roofline). I do want the best 2.35:1 experience possible, and I'm already making 16:9 compromises by having bars on the left and right, which don't bother me at all. I'm not sure I've seen the barrel distortion talked about here so I don't know what to look for with regard to that. I wouldn't want to render HDTV viewing unwatchable for the sake of only slightly better widescreen viewing.
I'm going to buy a screen in the next few weeks. Apparently the screen I wasn't isn't exactly everywhere for Black Friday/Cyber Monday. LOL.
PS: While I'm at it, how far away form the projector do you guys put your anamorphic lens? In my last theater, I never could get the same sharp focus in 2.35 mode that I got in passthrough mode but my lens was so close to the projector lens that they actually touched slightly. I'm wondering if that was the problem and I should have allowed an inch or so between them.
