Perhaps you are suffering from a bout of GAS?
If you have an 85L, 100L, and 70-200 II, you 1000000000% don't need a 135L.
5D2's AF system is 100% fine. Do you really need to spend hundreds of dollars to move your servo AF point a smidgen across the frame? If the answer is really yes (really?), I'd get rid of all the lenses in your signature except the 85L, 100L, and 70-200, and put the money towards a 5D3.

Stationary targets I agree. Otherwise it is not good if you need to shoot outer points and fast apertures.
