I was fitted for C16 irons and driver last Spring. I recently asked my pro to replace the grip on my driver. He said originally they were to send the driver with the counterbalance (20g) to Titleist to be re gripped, however they are now being told that Titleist is no longer supporting the counterbalance. My pro re gripped the C16 driver and put 20g lead tape in the shaft since he was not able to re use the original 20g counterbalance. This is no longer the same club I paid over $1,000 for a year ago. Two pro's and a local Titleist rep have not been able to tell me why Titleist is no longer supporting the counterbalance, nor have I been able to get a better solution than lead tape.
