I found it interesting, but inconclusive. The link about five and six sided molecules was obviously written by someone knowledgeable. However there were some holes in what he said. For example, a baby is born with six sided water molecules inside the cells(who cuts the babies up to find out), and post RO water has five sides, why can't it change on it's own?
The different experts all had different opinions on leaching/not leaching,/ leaching in a good way and removing toxins. It was all a bit undermined by the statement that the worst possible water to drink is tap water.
So in summary the divergence of views on this amongst the experts is very similar to the views we have expressed.
