The Benedictines definitely have a one week psalter Office that was reformed after the Council… ans presumably available in English.
Monastic schema B would be the easiest one week Benedictine psalter (the Cistercians also use it), as it has the entire psalter in 1 week. It’s what I use, most of the time; otherwise I use the LOTH if I am tired or more pressed for time. I don’t know of any English versions. Monasteries are notorious for putting together their own office sheets or books, in spiral bindings, or three ring binders, or whatever. I do know and have a French version, alas long out of print. Otherwise you could sort of concoct one using the LOTH for everything except the psalms and putting together a psalter from on-line resources. But you won’t have the common of monks and nuns if you do that, and not the Benedictine calendar either. Moreover, unless you’re a Benedictine (either religious, or an oblate), the LOTH is
your Office as well as everyone else’s.
Honestly, a 1 week psalter is tough for the laity. I can cope as I’m retired, but no way when I was still working (I insist on chanting the Office, at least when at home). Schema B does all 150 psalms in a week. Schema A does them all with many repetitions so you pray 250+ psalms in a week. Way out of my league and in fact way out of the league of many monasteries these days what with ageing and declining communities putting a greater burden of work on fewer monks. For most the LOTH is good.
For the OP if you don’t like today’s hymn, the Latin hymn is unchanged from pre-Conciliar days. You can use the Liber Hymnarius (in Latin).
That said, I am a huge fan of the current LOTH, as is most clergy that use it. It’s simply way more realistic for today’s realities. The trend to simpler offices for diocesan clergy in fact started under Pius X when he simplified the Divine Office from the 250 psalms (very similar to the original monastic Office) of the prior Office, to the 150 of his reforms. Even then, that wasn’t enough. We have to remember that in those days, a parish rectory would usually have 2 or more priests to share the workload. Now it’s not unusual for one priest to share 4 parishes.
There are many, many improvements and restorations of tradition in the LOTH as well in spite of the shorter psalmody (one can argue that the true tradition is a fixed number of psalms over a fixed time span, as the Desert Fathers prayed all 150 in a day!). It would take another long post to list them all.
One of the most important points to retain about the LOTH. It’s not all about me. It’s the
public prayer of the Church for all of her members. We join in that prayer, not the other way around.
