I thought I remember seeing a "real" flexible liner when I was looking a few years back but I can't put my finger on the source.  If I read their add correctly back then, the liner they sold was able to bend with ease, unlike the typical flex liner.  It was almost "slinky-like" in it's ability to really flex.  Does anyone know what I'm refering to???
