All the pressure and force of a FFF blow concentrated over a shorter bearing surface and segment of wire has far more potential to break a string.   Keith Roberts </BLOCKQUOTE> Yep, I agree. Sharpness of profile plus angle of deflection. I don’t think hardness enters into it, unless somebody can show me how. I don’t see how softer metal would make a sharp profile with a high angle less apt to string breakage. Maybe it does, but I don’t understand how.
