I use ritual of returning in communions - its part of what I keep meaning to include in a guide.

You can do something like

Master A.
CM RoR Big Spell 1, Trigger Spell 2.. Spell

Slave B
CS
Slave C
CS
Slave D
CS
Slave E

Mast B
CM
Slave F
Hold Hold Hold CS
Slave G
Hold Hold Hold CS
Slave H
Hold Hold Hold CS
Slave I
Hold Hold Hold CS

You stagger your CS so that your entire communion doesn't get exhausted by the first spell (only the first half). You can then trigger your exhausted slaves to return home via the trigger spell.

Things that are not covered in the current guides are:
Staggered communions,
Proper use of Relief type spells. Jomon's invigorate spell, and mans spell songs are WAY stronger than commonly considered.

Staggered communions can also mean you deliberately kill a couple of communion slaves to prevent exhaustion ni the rest.
