We purchased the 66 to 120 inch rod to run curtains across two windows. I knocked 1 star off the rating because this size does not come with color options - you get black; that's it. I would have preferred bronze to better match the decor and fixtures of the room. This size does come with a center support. This rod is good for light- or medium-weight curtains (we have medium); personally, I wouldn't attempt to hang heavy-weight drapes from it.
The rod installed easily and wraps nicely around the ends, so if you need to block out pesky sunlight in the early morning, this rod should work well for you.
