Yeah, from a review that I've read, the Firehawk is better at rejecting light coming in from the sides, while the Black Diamond is better at rejecting light coming in from the ceiling. In my case, the daytime ambient light is coming in from the rear right side of the room, so the Firehawk sounds like it would be better for me. Stewart's web site says that the minimum throw distance for the FireHawk G3 is 1.6 x image width, while the minimum throw distance for the FireHawk SST is 1.4 x image width. A 106" screen is the biggest my room would be able to handle (can't fit a bigger screen in). A 106" screen has a width of 92.5". My projector is about 11' from the screen, so that would be a throw distance of (11 * 12) / 92.5 = 1.43. So, it sounds like a FireHawk SST is better suited for my throw distance than the FireHawk G3. The SST was supposedly designed in collaboration with Sony (back when an old Sony VPL 50 projector came out). The SST's gain is 1.1 while the G3's gain is 1.3. I've read that hot spotting becomes more of an issue at shorter throw distances, so the SST, with its lower gain is more suitable than the G3 for short throw distances. So, sounds like the SST is more appropriate for my needs. Probably not an issue, but I'm wondering what if I were to replace my projector sometime in the distant future (if and when 4K hardware & software become more ubiquitous) to a new projector that is not a Sony, whether there is anything inherent in the SST that wouldn't work as well on a non-Sony projector as on a Sony projector.
You mentioned "If you don't care much about 3D, I would go for a 110" Firehawk". What do you mean by "if you don't care much about 3D"? Is it because the larger the screen the lower the brightness, thereby making 3D even darker? I can't fit a 110" screen in my room anyway. 106" is the biggest I can hold, unfortunately.
