I suspect the MFR checked this forum before replying to me and said, "hey that's brilliant!"
That would sound about right.
Seriously though, glad to have helped. Report back with your progress.
I'm pleased to report that I completed my installation of the floors. Thanks again for your suggestions.
I also wrote up a tale of my experience on my website: http://matthewcoolidge.com/2009/11/0...loating-floor/
Glad it all worked out.
