Correct, this model is not available as retail although it would be one I would certainly try. It is supposed to spin more than the ProV1x and feel a bit softer. As for the writing, that would be someone’s own personalization.

No idea

It may be Brad Kennedy’s ball. He plays on the Japan Golf Tour.

The Pro V1X + is tour-only ball that gives players the high flight and trajectory of the Pro V1x, but with a much softer feel and noticeably higher spin rates, particularly with irons and wedges.

Seek and yea shall find.
