Mark, was any recommendation made to switch tires and wheels? It's my understanding that the GSP9700 can also be used to match the the "severity" of an out-of-balance condition between wheels and tires. In other words, the most out-of-balance tire can be forced matched against the most out-of-balance wheel to result in a combination that results in the best overall balance prior to the addition of wheel weights.

Were you pretty confident in the technician's ability to operate the 9700? I've had a previous set of inexpensive tires balanced on a 9700, at a shop belonging to a nationwide chain of tire stores, with less than wonderful results. I still have the nagging suspician that the technician really wasn't aware of information that can be obtained using the 9700.

Thanks for the great information!!
