Tradition NLP: find people who demonstrate excellence and using various tools create a model out of that excellence. Teach it to others.
DHE: use the same tools and distinctions to experiment and create new patterns rather than relying on other people to model them.
That's the basic distinction between the two, I think.
Really, DHE is just Bandler. That's all.
I'd watch saying that you didn't learn anything from the DHE tapes. Bandler has a way of sneaking up on you.
That is, he does a lot of "unconscious installation."
If anything, you can learn mad language pattern skills from Bandler. He is very sophisticated and layers techniques all the time. A lot of tonal anchors and chaining states, too.
