Is DFS necessary?

Last night was my best fireworks night ever, photography-wise. One of the best things was being able to turn off dark frame subtraction on the K10D. I figured I'd do the noise reduction in post. But I didn't need to! I don't see a lick of noise in any of my shots. Take this one for example:

That's a six-second exposure. Look at the full version and try to find the noise. Straight from camera JPG, cropped.

I didn't use NR with mine either, and ACR seems to have removed the hot pixels that my K100DS gets during long exposures.

Wow, I'm impressed! I love fireworks. I'm curious what lens did you use and at what aperture and also did you go with a high ISO?
