But I think that Robert Dilts and Richard Bandler probably deserve the credit for inventing submodalities. Dilts first discovered them and then Bandler starting using them to develop techniques. NLP Comprehensive was certainly still selling those tapes as recently as a few years ago. I found David Gordon an extremely disappointing and lackluster teacher during my Master Practitioner training. However his course on metaphor, available on tape, is certainly very good.
Different trainers are so different from each other.
I took DHE from Rex Sikes last summer. Rex is an excellent teacher and a lot of fun. From what you say, he might be an excellent choice for you. Incidentally, Rex is a former Hollywood actor and screenwriter. For someone who is a therapist or wants to be one, I strongly recommend Leslie's two videotape sets, sold by NLP Comprehensive.
