I was introduced to LEAP before I heard of Infinite Banking. The latter is a concept, the former is, ultimately, just software designed to get to the same place. In my experience, those who have not mastered the concept, who do not know it well enough to teach it without a computer, then the software is a very bad crutch.
That said, if you sell cash value life insurance, then you should know about LEAP, where it works, and where it doesn't.
