There are some time that I use Balistol. It's wonderful in order to maintain the center pin very well. It's best use I think that is in places that are full of humidity. To compare with Protek I used in my own grand some pins with Balistol and others with Protek. On the beginning the action was with the same weight but after some time, centers with Balistol was free and some others with Protek was not so free Rogerio Cunha IC Member of The Piano Technicians Guild http://hpp.ajato.com.br/rogeriocunha
