I have a 20 x 40 with a 14' hight and it is about 10 years old. It has held up well in the past, but a couple of years ago, one of the heat sealed seams opened. That is the only problem with it that I have ever had. If the new ones are as good as the old ones, then it would be great. If the new ones have material made outside of the US, then I guess that they won't hold up as well... just like everything else made over seas...
