That is exactly what I was thinking. Especially since a lot of the hybrids, if not all, are made by companies that also make popups, so they should know what they are doing. I was thinking maybe it was the seal where they fold up and while they were stored they leak, but that would be easy enough for the manufacturer to figure out and correct.
Maybe it was the case of one hybrid leaking one time and now everybody thinks it is a big problem, you know how the grapevine works.
Thanks for the responses, I will keep looking.
