I wonder how the Mysteries of Light are bedding down. My own reactions were conflicting: respect for Roman Pontiffs and especially for JP2 as against a feeling that practically it made the distribution of the mysteries on weekdays complicated and unnatural, and historically it subverted the old and lovely notion of the Rosary as our Lady's Psalter. I soon slipped into a habit of occasionally adding the M of L to the usual mysteries, and of sometimes substituting one or more of them for one or more of e.g. the Joyful Mysteries. It had in any case been my habit to substitute occasionally other Mysteries (such as the Immaculate Conception, Presentation of Our Lady, Birth of John Baptist). The actual selection of Mysteries was of course quite late in the history of this devotion.
I have a personal eccentricity of treating the Our Father of my daily Mass, and the three Hail Marys in the Prayers for Russia, as the start of the first decade I say each day ... so as to have the daily Rosary springing out of the daily Mass. How wrong is this?
