I'm going with the impact kit (much cheaper than Manfrotto). I guess what I really need to know is whether or not the roll of paper has a solid core?
It almost certainly has a hollow cardboard tube. Although it's heavy-duty thick cardboard, it will sag over time if it's only supported at the ends, with no crossbar.
If you take it down and store it upright after each use, it should be fine. If you leave it hanging by the ends, it will sag and get semi-permanent waves & ripples in the paper.
