Thanks for that. I read through most of it. What interested me...as someone who likes and uses Bick4 ...is that the rep for Bickmore explicitly stated, at least once, that none of their products contained silicone. And implied the same another couple of times. I was also interested in his comments about Bick5--he said it was essentially a more viscous (thicker) version of Bick 4 and that Bickmore recommended it for exotics.
