If you haven't seen it i would say sit in the center section even though it is slightly further back. If you sit in the center section you get to take the projections in more head on.
Personally though i would sit in row a because i hate the projections then i could focus on the actors more.
well i have seen it 7 times in london before so i really don´t care about the projection I´d just like to see the actors up close as much as possible and since the front seats in orchestra are all taken and those are the best seats I could find.
I´d prefer row a as well but I just don´t know how the vue is from far right. It´s nearly the last seat in the row. Get what I mean?
