which is the better out of frame pipes for a 4mill banshee, shearer, or RDZ?
From what I was told. Matt made the pipes for A&S and RDZ a few years ago and then they found someone to make them cheaper or whatever and they are stamped copys of the older handconed shearers. The new shearer pipes are supposed to be a slight improvement over his old design. So I would think they would work very well but shearers newer ones would maybe be a touch better.
