As I said, if you have attended Mike's workshops, then I would suggest going to Dan's. Jim, you should go. I think you'd absolutely love this stuff. For everyone else, I highly recommend attending Mike's, Dan's, and Ark's workshops. The similarity and difference can be experienced firsthand. Not saying good or bad but I've found differences. Everyone will. IMO, that's something best experienced directly.
Mark, have you ever trained under Mike Sigman? If not, please qualify your statement above.
Are you going to answer Jim's question?
