I have a few old booklets that sound like what you describe - one of them if the Million Dollar Move Collection and another is the Stretch Gain Angle. Unfortunately, the author doesn't put his name or contact info on either one of them and I can't remember what it was.
Maybe the names will job someone's memory?
