I’m thinking about getting a protostar, but I have 2 questions… ???

1. Can you grind(regular and thumb) with it just as good as say… a DM?
2. Where can you get another one of these “center trac bearings by CBC?” Help would be appreciated.

It can grind but not well and is tough to get a good thumb grind  
It doesn’t arm or thumb grind quite as good as the dm or dm2

You can get a CBC center track here at yye
