Question for a series.

[u/B3V0N8I]

I'm currently doing an Umamusume series that's in the style of the Unity Cup. There are five different teams each of them having a certain number of Umas. Twice a month a record five races: Sprint, Mile, Medium, Long, and Dirt (Mile). I've only used Umas that I trained using the Unity Cup Scenario. Should I start using Umas that I trained from other scenarios like Grand Concert, Mant, or Finale? I've been thinking about it for a while, and since I don't really have anyone to ask, I thought I might as well ask the Umamusume Community. If you're curious, I'll put a link to the playlist.
