Ok... since no one has really answered the question the way I want it...

Let's rephrase it...
There are 3 70-200 on the Canon market...
one is 4.0-5.6 (I may have the numbers wrong, but it's in that range), and 2 are 2.8.
The 4.0 is very affordable, but not suitable for my needs (need fast speed).
One of the 2.8 can be affordable with a loan, the other one, not so much....
So basicly, the 2700 $ lens is not so much an option, and the 4.0 either cause too slow.
That leaves me with the 2,8 at 1300 $..
Or..... within the same price range..
The 100 macro 2.8
I know I was not always shooting at 200 mm on the show ring (horses I mean), and sometimes I was just shooting wide and cropping the image on PS afterwards, cause it was more convenient.
It is hard to have the focus point exactly where I want it, when the horse is galloping and all..
I may rent the 100 2,8 macro and try it out at a horse show and compare...
What do the pros here think about that?
This is an example of photo taken with the 2700$ lens:
