There was a whole lot of information in the statement. I also do not see anything arguable about it....never really thought about the seam in the backing....but can see the problem with pinwheels, been there on that one.....
I still think that you need to check out the LAQ kinda like you would a contractor for your house. How long have they been doing this as a business, pictures of their work, ask for references....after all you will be giving them a piece of your heart....
