I like this youtuber pretty lefty from this and other videos I've seen. Also I've found the info in the builds useful when playing dnd.
Better to check out the video then me trying to describe how much I like him.

In one of his builds for tmnt he more or less mentions that had he gone full monk it would be too out there for what the the turtles can do so more flavor instead of powerful.
