Same as mr. unregistered, I level 1 of each type at the same time tho it depends on what lv manyu I have. I usually stop using lv5 manyu if the girl is at lv40 and only use lvls 20 and 100 till max. Same thing after evo tho I stop using lv20 manyus after lv60. (I do max non evolved 1st before leveling the evolved ones)
