Thanks for the reply. I'm getting the feeling that prolo is used much more in Europe and starting to be used more in the US.

I've only been in PT for three weeks, but it's been bugging me for three months. Maybe I should give PT more time?

I found two recent articles on it in the WSJ and the New York Times.
