Have you handled a larger great white? I'd suggest that you do and decide if you want a hand holdable or not.
The 400 is ii us m and 600 ii is usm are for me marginally hand hold able (and thus less good for difficult birds in flight). I have no experience with the 200-400.
The 300is ii usm and to a lesser degree the 500 ii usm are hand holdable and the 300 for sure takes extenders really well. The MTF would indicate that the 500 does so very well as well.
So Id go for the 300 or the 500 unless you are in very good shape in which case any of the great white sharks would work for you. If I were to buy a 500 I'd consider camera canada as they have a deal on the 500....
Sometime soon I'm going to the b&h super store in nyc, so I'll see how they feel.
