I used to have the portable Dalite with Wide Power material. Material was very fragile and thin. It had a 2.4 gain and hotspotted with bright material. Picture though on this material is bright and vivid like a plasma due to its reflective nature.
The elite screen is more film-like. Not as punchy but more natural looking. The material is rather thick and durable. Screen gain is not an issue. My Optoma is only 800 ansi. I believe yours is much higher. You would most likely need to take your brightness down to give you that large contrast ratio. No issue with light drop at any angle in my 23' long x 18' wide(25' at the back) room. All in all I am happy with my elite. 1 small 2mm mark on corner which cant even be seen in the dark. Electric to boot for under $400 cdn. Seeing my visitors drop their mouth as they see the 100" screen come down automatically...priceless.
