@ajl, it seems to me that what you're asking isn't about the performance or design differences between one set of irons from one manufacturer versus another, but simply what the difference between a premium set of golf clubs and a generic or a knockoff set is?
The answer, as in all products in life, comes down to quality. A premium manufacturer cares if their manufacturing process produces X% variation from club to club which can result in differences in performance from set to set. A clone company won't and they know their customers don't, so they don't invest the time or money into having higher manufacturing tolerances.
Anyone else see this? Anyone tried one? If so, thoughts?
