I intended for the Titleist Staff to answer this question!  I guess they are leaving it to someone else?

Hi Bob,

Thanks for the post and sorry for any delay. As you can imagine, we do our best to answer all of the questions we receive as promptly as possible but we also want to make sure that the discussion boards are place for golfers to connect with each other as well.

In regards to your question, there are a few players on tour that take a little more time than others to transition into new equipment as it is launched. While our team works with these players on the transition, some will continue to use a prior generation product and our team will provide that to them if it is still available. 

All the best,

Mike
