Isn't the marvel just a symmetrical VG with a different grit.. not entirely the same but I bet for most people it will roll the same given that most people layout asymmetricals so that the MB pretty much has no effect on the reaction.
Put a double thumb drilling on the marvel and take it to 4000 and you have yourself a VG..
