I can try the following at the weekend if the weather is half way decent (and if I get myself prepared for a trip to China on Tuesday)

1. D4 + 400mm f 2.8 ?
2. D800 + 400mm f 2.8 ?
3. D4 and D800 with 200 mm f2 and TC 2 III
4. D4 and D800 with 300 mm f2 and TC 1.7 II (I don't have a 1.4)

i can probably borrow a D7000 to try with the above combination
