well all three have overheating issues.... so they cool down together.... 
Im not saying you cant use it. im just saying i would prefer not to use the 5DII, GH1, or 7D as a primary camera.
if the producer is demanding it i will explain why not to use it.... but if he cant be swayed, 5dII it is... i jsut shot a music video on 5D II and the producer specifically asked for it. I shot it anyway, and we had overheating issues, monitoring issues etc...
the footage looks "great". It really does, but if this was going to be broadcast, i would have fought for a EX1 and SGpro only because of the compression that becomes evident in the shadows.
That being said it was awesome to shoot at a 160ISO, and have a super clean image. that was fun
