Shooting a portrait of church choir

So how do I go abou it?? Choir is 4-5 rows deep and about 30 (+/-) wide...

What I have to work with: Canon 5D mk2, 24L 35L 50, 85 B800 + small flashes or studio lights (some cheap brand)

I'm thinking to shoot with my 5D2 and 24L at about f8-f10 if I can get that much light in... B800 with white umbrella on one side 540ez x2 on the other side. Anyone who has done this, please help out! Where do I focus to get the best DOF?

Thanks!!!

Really?? no one has shot a choir before?

.. you'll be a bit short on light with 1 b800 on white umbrella on a 30' wide group f/10..I think

carefull with faces on the sides on 24L..

let us know how you worked it !

How did it ever go with your shoot? I did something similar recently, but I had a XTi and 2 Elinchrom 600s trying to shoot 60 kids on a choir loft. It was a rough one.
