Gee, I have all the tapes you've mentioned. I find the Beliefs to be almost as effective as the IPM tape. The Belief tape is no more specific than any of the other programs. I suspect they are designed so that they can be or more use.
You can get the Belief if you want. Different tapes have different relative effects on people. The same basic ideas are often express several ways. However, it usually one of those expressions that hits the bullseye. It probably a different phrase or combination of phrase for each person. We all start at different places when we use the tapes, so it only natural that we see and respond differently to the material. Maybe Belief has the perspective you need right now.
For me I think the IPM is the one and only tape I need. The rest that I have are fine, but who knows in 2 years from now it may be the Belief tape I turn to for my goals at the time.
So I didn't help you decide but maybe you have a little more useful information.
Sending love,
