Also, I know you had some concern over the Wet Edge Signature Matrix feeling rough. I know it all depends on who installs it, however ours feels great! Even my husband who has very sensitive feet was pleasantly surprised. And while I believe it really depends on the abalone shell the builders use, my pool builder did confirm that over the years they can tend to lose their sparkle. From what I read on here with people who are happy with it, they haven't had any loss of sparkle. I just didn't want to take a chance which is why I went with the glass. It gave me the sparkle I wanted and I don't have to worry about it breaking down, losing shine, to etc. Sorry! I don't need to confuse you yet again but just sharing what I've learned through this renovation.
