Treatment vs. Orientation ???

Regarding treatment and mix position orientation L vs W: In a very small room with nearly square dimensions (10'8"L x 10'0"W x 7'8"H), which is better - facing a long wall that I can better treat OR facing a short wall to take advantage of the additional 8" length of the room? I'm assuming the former (face the wall with the most treatment) since the room response length-wise and width-wise is nearly identical (I plugged the dims into the node-calc spreadsheet). I'm considering facing the long wall with the window. I can place semi-permanent corner traps on this wall and I can place temporary corner traps to my rear (the wall with both doors - entrance & closet) whenever I'm mixing. As far as putting up ceiling and side wall treatment - it's pretty much a case of "six of one, half dozen of the other" no matter how I'm oriented. I'm in an apartment - so anything permanent is not really an option. Just wanted to see if my thinking is in the right ballpark on this. If any more information is needed to help answer the question - please let me know - I was trying to boil it down for the sake of brevity.

You're only talking about an extra 8 inches? Your room is more or less perfectly square. Personally, because of the doors, I would set up the mixing position on the longer wall and treat all your corners with bass traps. They're mounted just like pictures and you're left with only holes in the walls where the screws went.

Thanks SonicClang - pretty much what I thought - just wanted to confirm though.
