It's interesting to note what Mr.Payton isn't saying and I suspect what he isn't saying is that with increased R&D costs and reduced racer numbers due to the greater costs of racing a 4 stk. he's making less money.Not that this is solely what motivates him but that "The writing is on the wall",that the new generation of 4stks are reducing participation in the sport and that it affects everyone involved in the sport.
