This has been discussed before in this forum, and there are different opinions. I stick to what I have claimed earlier:
It's definately a question of either F1
or F2 in my opinion, as they will give you the best view to decide the precise moment for take-off and landing, as well as the best way to judge if you have a good angle between the jumper and the skis throughout the flight. All of this is hard to see in other views.
Whether you should choose F1 or F2 I would say is more a matter of taste. Some will certainly disagree, but there are jumpers here who have become very skilled and successfull with both of those choises.
Personally I jump with F1 only. But I would say: Simply pick the one
you feel good with
