VR has more snap. It is more for medium-heavy with its 4000 Abralon cover. It can cover true heavy oil with a duller finish, like 1000 or 2000 grit Abralon.
Maxx Zone requires much more oil to retain energy. It is a true heavy oiler with its 600 grit finish. With a finer finish, like 4000 Abralon, it can handle less oil and have more backend.
