Oyajitchi, I'll say that in my opinion, Watangashi-hen and Tatarigoroshi-hen are done a bit better then how the first arc was handled, and that the last two Arcs were definitely the best as far as the VAs performances go. But it's really up to the listeners preference to decide when they find a performance acceptable to their standards.
