Firstly, they are a very nice set that you have there.

 

But it's not a question of being bored but there's really nothing that I can comment as I don't have either lens.

 

However, I do have the 70-200 f2.8 II and can say that it's the best versatile lens that I have. I imagine that the 70-200 f4 is pretty close.

 

The 100-300 seem really good so I would suggest that you stay with it. I don't see any compelling reason to get a 70-200 if you are happy with the 100-300.

 

Of course if you are planning to get a D800 then I can definitely recommend the 70-200 II. The details, even on a heavily cropped image is simply mind blogging.

 

Here is a shot at medium size (5520x3680) 20MP but downsized (remember a full sized image is 36MP):

And here is the cropped:

So, it's not just about being able to crop but the details that are still there.
