You probably won't be too happy with a ball head for the 200-400. Yes, it will work. But you won't be able to use it loosely to pan moving planes because the lens/camera combo is so heavy the ball head will just keep tipping over. If you do get a ball head, put it on top of a monopod for shooting planes. This is probably outside your budget, but the Wimberly Sidekick head will do a much better job if you want to put the lens on a tripod.
The bigger, gimballed head is over $700 CDN.
If you get either Wimberley I believe you need a special foot also for your lens, which adds to the cost. This and the Sidekick put you just over $400 CDN.
The other thing to think about is protection for the lens. It's long and heavy, so sooner or later it's going to bump into something. It's also expensive, so it's worth a few bucks to keep it in good shape either out of pride, or resale value.
You won't have any trouble adapting to this lens. It's long and heavy, but it's intuitive to use and you'll have fun with it right out of the box. The instructions for using focus recall are a little vague, but it's simple: Put the focus mode button in Memory Recall position, focus on the point you want to recall, then push and hold the memory set button (closest button to the camera mount end of the lens) until the lens beeps. Now when you want to recall that focus point, just push any one of the four buttons around the front of the lens and it instantly returns to your preset focus point.
I find my lens vingettes a bit when shooting wide open, but ACR can easily correct this as it's very mild.
Happy shooting with your new toy...
