Major Components Decision. Where am I going wrong?

I close on the new house with the HT room next week. I've come to some conclusions on the major components and would LOVE to have constructive criticism and advice before I place orders.
I have a 17' wide by 19' deep by 10' high dedicated HT room. The first row heads will be 10 to 11 ft from the screen with another row 4ft to 5ft back from that. It is pitch black in there. No ambient light. All vertical projection angles are very good but there will be some pretty steep horizontal angles that close to a screen that size. Here are my component choices...

Carada Criterion 142" BW 16:9 screen. LINK(It's large. Going with a 1.5 gain screen to be sure the 5010 will be bright enough for large 3D image with some sizeable screen edge angles from the front row. Despite the rooms use for mostly movie viewing, going with a Cinemascope screen would make the occasional 16:9 viewing "only" 90" wide without some video stretching, which I hate. So I decided on the 16:9 format. May have to utilize masking on Cinemascope films if top/bottom white bars start bothering me.)

Epson 5010 (Seems to be best overall performance/price for a 3d projector to fill a 142" screen. Is there any reason to go to the "E" option other than eliminating a HDMI connection to the projector? Is there any good reason to go with a 6010 other than Anamorphic lens mounting capabilies? Any reason to consider another projector like the Benq W7000. Seems the 5010 is brighter and performs better on any parameter that's important to me.) Mounting the projector with a Peerless PRS-UNV.

Looking very hard at the Fusion Tribute 1015 seats. Looking for LOTS of guidance/suggestions on seating. These seem to have good reviews of both the product and the seller. Seem like good seats for the money. Tribute 1015

You can find more information on my HT build in my signature link. Again, PLEASE comment! All are appreciated before I plunge into this major investment.

My wife's motto is, "If you even THINK you're going to feel the need to upgrade something in the near future, do it NOW. It will cost us less." She knows me too well.

Good advice on the screen size trials. I may do that. In fact one of the other members here in Houston offered some white paper to use for a temporary screen. I think I pumped them for all the information I can in the Projector forum already.

SMB, I've gone through the calculations. At 11ft view distance, SMPTE suggests an 81" diagonal 16:9 screen. Yet the majority of the members with similar viewing distances have much larger screens than that and are very happy with the results. The post above yours is a prime example with a 2.35 136" screen at similar seating distances and he's very happy. I know you're a professional but I see more members breaking those guidelines than not and loving what they have.

Jeff, I would really like to do that. I'll drop you a PM. I really appreciate the offer.

And Jeff, I apparently had my Calcs wrong on the 16:9 width. Having a 108" 16:9 on the 136" Scope screen is making think that is the way to go. I think I can tolerate side bars on the occasions I watch 16:9 better than horizontal bars all of the time during movies.

What projector(s) would you suggest with the information I've provided. I'm focusing on needing a projector with high Lumen levels to fill a relatively large screen in 3D. Plus the 5010 seems to do a really good job in 2D too. Does the 6010 offer the features I need for a Scope screen application? I appreciate the input/guidance from a Professional.

thebland, with your and others input in this thread, I'm starting to lean back toward the Scope format. It concerns me that it will push me away from the Lumen power 5010 that I think I need for big screen 3D. If the 5010 indeed doesn't have the features necessary for use with a Scope screen as SMB indicates, would a projector with less brightness work on a screen that big in 3D? If it were only 2D that interested me it wouldn't be important, but I would like to have a good performing 3D system. I hate to think I would need go to a two projector setup to get Scope 3D and flexibility to do 16:9 on a 2.35 screen.
Jeff has invited me over to see his HT. He has a JVC 50 but doesn't use it for 3D, if I recall correctly. The 50 is a 1300ansi so I'm very curious as to what it looks like on the same exact screen I'm considering. Having him allow me to experience the screen I want with a great set-up is really a great stroke of luck for my analysis. Hopefully my wife will want our theater to look like his too! Ours is sorta "dull" in the "trim" category compared to his right now.

I will have a row of HT Seating for the front row on the lower level but the wife wants to put a couch and tables on the riser for the second row. So that will be movable. We'll put it where it works best. I'll keep the 6.5ft dimension in mind as I sort things out.

Thanks!

Compared to what the rest of the house cost, anything she comes up with will be minor.

The arched windows are part of the base architecture of the house. Square wasn't an option so I don't have any information as to the price difference. Sorry.

As demonstrated by petew's post, I am constantly amazed as to the breadth of knowledge on this site. Even an expert on window construction. Pretty cool.

Thanks Jvoth, we love the house. Again, I'm new to this. All an Anamorphic lens will do for the 5010 is stretch a 16:9 into a Scope format, right? If so, I really hate that. Also it would necessitate a 6010 purchase vs the 5010 which isn't necessarily a deal killer. The 6010 accepts the Anamorphic lens. What I would prefer is to have the screen filled on Scope inputs and white bars on the side with a 16:9 input. Would an Anamorphic lens do that?

doublewing, I've actually done some analysis of my movie seating preferences sans the tape measure. I know "scaling" the preferences isn't always accurate but I'm pretty sure 11ft from a 10ft wide screen is going to be close to where I want to be. In fact, my wife seems to want to sit closer than that 1:1 ratio. And I do believe/agree masking of some type is in my future.

Bottom line is coming to this: what projector/lens do I need to Illuminate a 136" 1.5 gain Scope Screen that will be bright enough for 3D and allow both full screen Scope and side masked 16:9 modes. Seating distances will have to be worked-out, but despite the SMPTE recommendations just don't make sense, at least for me and apparently quite a few others. But fortunately I had the riser in the room built separately from the floor frame, so it can be moved back if necessary for a front row distance adjustment.

PLEASE KEEP THE INPUT COMING!! Especially on the projector/lens selection. Should I push this to the Projector area?

Thanks for the input guys. That's good information. I'm really bummed it will take a $4000 lens to get full resolution on a Scope screen with a $3000 projector. Am I understanding correctly that the 5010 will not give full resolution on a Scope screen without an Anamorphic lens in front of it? Sort of mushy on that between the last two posts.
