I know testing it first hand is the best solution but I don't have ready access to any of these short of arranging a rental.
My only concern for the 70-300L was if the extending zoom was a weakness for water ingress. It is my first choice if that is not an issue. Got a reference to the level of water resistance? I know it is supposed to have some, but I'd want to know it is significantly better than the 100-400L for it to be worth considering.
The 70-200 II unfortunately is much bigger, heavier, more expensive, requires a TC, has shorter zoom for the only minor plus side of not extending during zoom. As I'm not sure about the 2x performance, I wonder if the f/4 IS with 1.4x might be a cheaper option for the middle ground.
