I have listened to Bill, read some of his work and used the first level of holysinc, I believe he is a genuine guy and seems to be well respected in the personal development field.
He is a business man though - nothing wrong with that, and would appear to have a different approach to business than Michael. Although his marketing appears to be a little aggressive and his products over-priced there is no evidence that he is shady, in fact quite the contrary,and having learned a few things from him, I am quite sure he would not do the dirty on anyone.
For me LifeFlow made much more economic sense and a year down the line I have proved to myself that it was the correct decision. There is certainly room for both systems in the market
