you know, I would have said the Old Orthodox Prayer book because it is like a mini Horologion and Prayer book all rolled into one. Now it doesnt have the lenten services per se, but it does have Matins, 1st, 3rd, 6th, 9th hours, Vespers, and Morning and prayers before sleep. Im really struck at how there are no little hours in every prayer book that I own except for the OOPB. That was always a pet peeve of mine. You might just have time to pray in the afternoon.... However. I prefer the morning and evening prayers of the Jordanville prayer book to the ones in the OOPB, and most every other prayer book. Neither one has compline though... sigh... The HTM and OCA prayer books have compline.
But the OOPB has the worst construction of the bunch. Newspaper quality paper and glued binding. Ugg. The UOC has outstanding construction and paper as well as HTM's. Jordanvilles is very good too (but I dont think the paper is quite as good) but they gilt the page edges. The one in slavonic is better constructed, laid out, and has two color printing.
So I guess My Ideal prayer book would be the quality of the Russian prayer book (or HTM or UOC with guilted page edges) with primarily the OOPB prayer contents, only substitute the morning and evening prayers with the Jordanville, and add Compline. A psalter isnt necessary but you could definitely add one without adding too much bulk, but since I have the HTM psalter Im not overly concerned with it. In the St. Andrews Book of Common prayer (which is made for and used by Antiochan Orthodox Western Rite parishes) it does contain the Coverdale Psalter, but they use bible paper and I would NOT want that. If you added the psalter to the UOC prayer book, it would be necessary to make it enlarge it considerably because it is written in Ukrainian and English, but if you did it in one language it would actually make the book smaller.
