I shoot weddings. The 24-70 is my bread and butter on the 5D2, but the 85 1.8 (the 1.2 is too slow) is what I use for portrait work or in low light. The 70-200 2.8 IS is what I put on my 70-200 2.8 Is, but if I need it, I will put that on the 5D2 at the reception for candids. If you were really needing to have the second shooter and gear, I'd get the 5D2, 70-200 2.8 IS and the 24-70. I use both cameras and about 5 lenses at a shoot and have at least 1 other person using my equipment adding a 40D. If I had my way, I'd be 3 people, 2 using 5D2's and 1 using the 7D.
