I have a 70-200 as well, but i tend to usually pull out my 100-400 before it almost every time. It's just always given me more reliable shots. So i usually let my friends borrow the 70-200 when we are all out shooting at the same time.
I end up at horse jumping events often, with the FF body, i find the bigger zoom just comes in more handy and leaves me with more room to play as i'm standing close to some jumps and far from others. and again, it's allowed me to catch the holes on the buckles of a jumping horse from the opposite side of a ring.
don't get me wrong, I like the 70-200, but that gap between the 24-70 and 100-400 is just too small to worry about covering in my opinion on a FF camera. On a crop body (witch i had before) that gap seemed a lot wider.
Mind you, the size of the 70-200 is really hard to beat for what you get. And the internal zoom is really nice to have.
Some people don't like the slider zoom style of the 100-400, so make sure to test one out before buying one if you are seriously looking for one.
