Either way in this description, the tarp fails. Whether it is at the sew line, or at the edge of the taped seam. What I am wondering is: Does one of these ways fail under less pressure than the other, or is it just different ways of failing? Was your reason for sewing and then taping just to elliminate the need to seam seal, or to add strength? Just wondering for future purchases.
