I loved my CC Gold series brush with the 27 mm pins. I hated the Fusion brush. It wasn't worth the money. I sold it after only using it a few times.
My new favorite brush is the Madan pin brush. I didn't think anything could make me give up my Gold Series brush, but it did. The Madan is used by show people and is the best brush I have ever used.
