re shafting 712mb

Do the 712 irons have a neutralizer dowel like other forged models? If they do is it in the tip of the shaft or the hosel.Does titliest have to do reshafting

John, 

The hosel plugs we use are inserted into the tip of the shaft and are used to adjust swing weight only.

Can I reuse the plugs if I'm going from S300 to X100?

Scott, 

We would recommend you send your clubs back to Titleist for any repairs, but they can be re-used if they aren't damaged in the removal.
