You have some good elements in each of those headlines. However, I would try and find a more intriguing hook. What's the story behind this? How did you discover this? What type of work were you in before discovering this system? These are the questions to ask yourself to bring out an interesting hook that will grab your prospect's curiosity. Remember John Caples' formula for grabbing attention: Curiosity + Benefit = Interest. By having a hook specific to you and your story, you'll make your headline unique ... separating it from all the clamor that goes on in the net these days ... and will make your prospects listen to what you've got to say. My 2 cents.
