A couple of questions.....Are there available any objective tests, like those done by Consumers Reprots, for instance, of the qualities of any of the various brands? How well does duct tape keep? The reason I am concerned is that i have a roll onmy hiking pole that is at least a decade old...I am not sure that at this point it will perform very well. Is any old duct tape better than no duct tape at all? Is "100 mph" tape even a valid category, or just a military slang term?
