As OF mentioned it sounds like PV may be confusing the HVD rework with the v2.5 top selling on D9's site. There was an issue with the release of the HVD upgrade where the top was not screwing on correctly. This is currently being addressed and that is why you can no longer purchase it on D9's site and also why the PV rep told you they no longer have any in stock or to sell. The HVD upgrade and top are different from the v2.5 top. In short the regular v2 top is a regulated 3.7v top, the v2.5 top is unregulated 3.7/4.2, and the HVD upgrade/top will allow you to use up to 7.4v. Read through the past 30-50 pages or so and you will find all the information you need. *EDIT: If PV has the matte black v2 get it you should get it and then get the v2.5 head from D9. This is what I would suggest if you are determined to get the matte black OMI with the 2 extra carts. (which might be old carts.. not sure?) Or pick a color? Good luck..
