RS2 and Da-lite Pearlescent

Hi,

I am trying to match a screen to my RS2 and would appreciate any help.
My screen is going to be 9 feet wide 2.35 CinemaScope (buy without a panamorph lens). I am going to sit 13-14 feet away from screen. Projector is going to be shelf mounted above the seating area. Room is all dark with black walls and ceilings and dark floor (but not black). I am going to watch only movies on the projector.

My questions:
1. I am thinking to use either Da-lite cinema vision or Da-lite Pearlescent. Which one is a better choice (considering gain and performance).

2. Is it realistic to project 9 feet wide image with that projector considering that bulb dims over time?

3. Is my sitting area too close to the screen considering its size (or in other wards, is my screen too big for my sitting distance)?

Thanks for any help

Thanks for your answer.
Is there any other screen from Da-Lite you would rather use with the rs2 instead of the cinema vision?

When people say the RS2 has 600 lumens they mean it has this number of lumens on the short throw or the long throw ?

Thanks for any help.

Thanks for your answers.
Projector is going to be placed above my head and i am intending to use the shortest throw. I was heading towards the Pearlescent or the cinemavision but since nobody here seems to like the Pearlescent and the gain on the cinemavision seems to be too low for my screen size i am looking for alternatives. Everybody seems to like the high power with the rs2. My question is can i fold the high power screen material so it will fit into a suitcase (I don't live in the US and i can't find it in my country so i will need to carry it back with me)?

Thanks to all of you.
I am buying only the screen surface for a custom made frame. In the past I took with me in the suitcace the high contrast cinema vision and it was no problem and the material arrived to my place in a perfect condition. I understand the high power is fiberglass backed (unlike the HCCV which is made of a flexible vinyl). Does it make a difference?

Hi again,
thanks for all your help. It is much apreciated here.
I spoke with the store and they are willing to ship it to my country for a fair price so I decided to go with the da-lite high power screen.
I have few questions:
1. How large I can go with the high power assuming it is placed on the optimal place or slightly above it (ignoring the fact that i am going to project from only 14 feet away. I am moving to a larger place in about 8 months and would like the screen to serve me at the new place as well). Can I go 12 or 13 feet wide (i am going to project 1:2.35 cinemascop but without an anamorph lens?
2.assuming i place the projector in the right place what am i loosing by going high power (black level, color accuracy, etc.).
thanks for your help.
