Interesting. I do most of my shooting with a D3, which can give me 9 frames a second, yet I never thought to use a burst on a wave. I guess the reason is that for a while I tried shooting birds on the wing with bursts but finally found that I had better success with single shots. Next time I shoot a wave I think I'll try your approach. It's a different kind of thing. A wave shape is developing, while a bird is just moving.
