I've discovered the Madan pin brushes. They are a well kept secret used by show people. I've tried them all, All Systems, the Chris Christensen brushes and I got rid of them all after I got my Madan. It is the best brush I have ever used.
They are normally sold at shows, but a member on another forum I belong to also sells them online. PM me if you'd like her contact information. The brushes are $16.95 plus shipping through Cindy.
Lainee Ltd. also carries them, but they are more expensive.
