buy an advanced stylus shape: Line Contact/Microridge/Shibata/SAS: they cost more, but last much longer
All these advanced profiles have far smaller contact areas with the disc. So the friction is concentrated over a smaller area and the pressure per unit area will be greater, thus wearing the stylus (and disc) faster. Furthermore, advanced profiles deliver their performance improvements because the contact area is small and the disc is thus 'read' more faithfully. The fine line contact soon enlarges with wear and some of the performance edge is lost.
It is important to remember that something can rarely be had for nothing.
