I was talking about the contact area and how much more contact there is with the MRL set up. Their set up looks alot more stable than using spacers etc after machining the caps down with the Hughes set up on stock caps.
Its just the way you worded it then, I was just trying to make it clearer for anyone reading that the girdle didn't make the difference in contact but the caps do. Not trying to be an azz, just trying to clear that up :-D. I'm not sure if Mike makes his own girdle, that might be a Hughes in the pic. When I ordered my caps from him I don't remember him asking if I wanted a girdle or not.
