I kind of have a good grip on how to do MS now. Obviously, the earnings come in the form of cash back or miles earned. However, I feel that the lion share is being paid out of Amex. For example, Serve/Blue Bird, Redbird, Old Amex, Amex GC and other ones such as Amex sync, starwood.

I know chase/wells, etc are out there but the easiest seem to be Amex. Will this form take down Amex?
