Not sure if there is a question here. The Pro-V balls are made in Titleist plants. They are the standard for consistency from box to box.
That DTC vendor has a history of back orders as all of their product is ordered from contract vendors. Since TM bought one of their suppliers they are contracting with other contract vendors. Some of their lines will be changed. If consistency matters, there is no comparison. Might be appropriate to say you get what you pay for.

The Prov1x left dash is an incredible performing golf ball.
