Dr. Schulze/Sam Biser

Could somebody fill me in on the politics between Dr. Schulze and Sam Biser. It seems unfair that Biser has propietary rights to Dr. Schulze 's knowledge (Save Your Life Course), yet he bashes Dr. Schulze several times on his site. Also, why are Dr. Schulze's videos not as thorough as Biser's and how did Dr. Schulze allow this to happen?

I am torn as to whose videos to buy. I greatly admire Dr. Schulze, yet want the most bang for my buck, as it were. Tweet
