I just wanted to post a little more about the Ball Baron. Iv'e been following this thread for a while trying to order a good set of pinballs for all of my machines. I finally decided I didn't want to wait any longer so I ordered 4 carbon balls for my Met from Ball Baron the other day. This guy is great. Shortly after I place the order he calls just to let me know the carbon balls are not as shiny as the G10 or the standard chrome balls he sells. I told him I understood and that was why I was only ordering enough for one game while I wait for the Ninja ball to come back into stock. He proceed to get very technical regarding the different metals and why he is having a tough time polishing the carbon to the standards of a chrome ball. Long story somewhat shorter, he tells me he's going to send me two polished carbon and two unpolished carbon so I can see the difference. When I received the package there was also an extra standard chrome ball so I could see the difference. Here are the pics of the pinballs. I don't see much of a difference between the polished and unpolished carbon, but I do see the standard chrome is a bit smoother.
