Dude, 10fps is absolutely firing. My D5100 shoots at 4fps and I get way too many photos. I shot over 500 frames on these two days. At 10fps, I would certainly be over 1k. Of course it's better to over shoot than miss the shot. You can always delete. It's a problem I am glad to deal with.
I've tried the electronic view finder thing an it sucks. I need some sort of optical view for framing the shot when shooting action is all.
One thing is for sure. Get the camera you are going to use. I do like those cameras and they certainly can work very well for what you are doing. Don't get me wrong. I'm just a crusty old fucker is all...
