To maintain the playback fidelity of your mono record you really need to use a stylus designed for mono records. The 1.0 mil mono stylus is the standard for mono records. A very common misconception is that you can use a LP stylus for playing mono records and obtain remarkable results. You cannot because the LP stylus is narrower than the 1.0 mil mono record groove, hence the tip will slide to the bottom of the groove where debris has collected for many decades. A LP stylus will also slide side to side and will not trace the grooves properly. The use of a LP stylus will thus result in poor sound quality and extraordinarily high surface noise.
