Hi all,
Here are a few questions I have in preparation for the airshow season (my first one):
1. I'll be using a 70-200 f2.8 IS - is that enough reach, or should I plan on acquiring an extender? If so, should I go with the x1.4 or x2.0?
2. Will I need a monopod? Can you even keep track with fast jets using a monopod, or do you find it limiting and prefer instead to go handheld freestyle?
3. What is avg./most used aperture for these kinds of venues? Assuming it will be sunny, should I go wide open on the aperture and fastest shutter speed to keep up with the jets (excluding the case where prop blur is required)? Or should I stop down the lens a bit?
4. What mode do you think is the easest to work with at these speeds? Do you usually keep it in TV to control motion or do you prefer going Manual on it?
Any other pointers will be greatly appreciated. 
Thanks.
