Oooo, you have some big boy stuff there, very nice.
The 70D wasn't around when I bought my camera 2 years ago.
My choice was the 7D or 60D, I wen't with the newer technology.
I love the cameras great low light capability and at 18mp I can crop closer with no or very little loss.
I really like the 10-22, chromatic aberration isn't too much of an issue it's easily eliminated in lens correction with ACR in Photoshop.
It is a crop sensor only lens you can't use it on the 5DMkII, I don't know what the full frame equivalent would be.
