As long as we're on the topic of pooping in the woods, as it were... Has anyone used both Restop and Double Doodie products? If so, is one particularly better? We've been using a Luggable Loo bucket with the Restop 2 bags for the past year, but as I'm about to be out and need more, was looking at the Double Doodie brand bags since they're a bit cheaper. Just wondering if there's a marked quality difference.
