Looks very good on the Exped
No official top or bottom per say, just have to flip and twist if it does not line up. Long term compression is hard on climasheild. I would avoid going down to the max in a compression sack if you can avoid it. It will cause the CS to break down over time, though it will take a good long bit of time before you have a problem.
I prefer to not compress the quilt a lot and pack it loose and let other gear squish around the quilt as it will better conform to the shape of a pack or bag.
