Depends what I'm going to be shooting, but I like at least 400mm and as fast a lens as possible (which usually means f4 with a 300mm f2.8 + 1.4x teleconverter) but having a fixed focal length means either a 2nd body with another lens attached or juggling changing lenses...and the latter is not much fun.
I've never fancied taking my 600/4 to an airshow, the need to take large & heavy support complicates mattters further.
I usually have the 300/2.8 + 1.4 tc on a body with a 1.3x sensor crop and a 70-200 f4 on a full frame body.
