The lightest weight option is going to be the Rockville Facade. You buy the 4 panel facade, and then they sell a 2 panel add on. I use 1 extra panel to make 5 panels and it works great for fitting completely around a 6' table. It also fits in the carry case that it comes in still. You can get 6 panels in the case (It will be a tight fit with 6, but it does zipper up and fit in there.
