Sim Build Advice on screen size (GC2)

[JesseGoodier]

Thank you everyone who has posted and shared information, hope that I can help others as I continue my project.

I built a house to put a simulator in the basement. A few issues during construction, but should work just fine. Ceiling height at hitting area is 9'10"

Looking to make this a really nice environment for golfing and tossing back a couple beers with friends.

Just ordered a GC2 from Golfsmith for about $8,000.

Biggest concern:
There are I beams that I'll need to contend with. Bottom of I beam is 8'10".

If I do a 16:9, I would have a 15'8" x 8'10" screen.

Do you think I should do that, or go to a 4:3 and get a 12'3" x 9'2" screen?

I won't be using it for movies.

I'll try to attach a picture. All comments/advice welcome.
