#3 is great. I just edited an autocross event, started with 391 raw images and came out with 169, and this is, for the most part, basic shots, even at 169 I left in some mediocre images because the drivers still love to see their cars at different angles, though as I've shot and edited many events, I see repeat cars and once I get a "knock me out" shot of a certain car/driver, it's really hard for me to keep another so/so shot of the same car.
