I have used the Ken Brooke routine for years, as as personally taught to me by Ken Brooke.
FYI there is a set of Ken Brooke bottles on ebay right now.
However, I am sure what Denny offers here are fine. A little puzzled by the photo showing 12 bottles and the text says 9. He's right about the tubes to get.
