Jeff, I am a low volumne restorer..meaning I only restring maybe 3 or 4 pianos a year...But my experience is...if the block is good, especially in a full fit piano like the S&S...(I have very little experience installing the full fit block) I have had exceptional results with the fine quality of the Lo-Torque pins. It seems the old argument about over-size pins had to do with the increased diameter of the pin, resulting in less fine control of the wire...and that is a realistic complaint. I think the Lo-Torques are a 'better' pin than what comes out of most pianos....Yes, they are more $$$. I don't use a gun brush...or a reamer...Though,a reamer(done by hand to avoid heat?) would give a consistent hole size...!
