I think it's actually nice to sprinkle Vesperal Liturgy in a few times per year. We take the "Matins then Liturgy" thing for granted in the Roman/Greek tradition, when it can be done after Matins, after 6th Hour, or after Vespers. It certainly is more common than people realize, though: the pair around Christmas & Theophany, the pair in Holy Week, plus every Wednesday, Friday, and non-Annunciation weekday feast in Lent. It's a nice change of pace.
