Canon 7D with Canon 24-105mm f/4L IS, USM, f/11 at ISO 100, Bulb Mode, 1 sec. I specifically chose the longer shutter speed to capture the trace, and used f/11 to create a black sky (wasn't particularly interested in brighter and wider trails). As to the "Finale", I agree with you, shutter speed needs to be significantly shorter so as not to blow out the scene.
Having just re-read this, I discovered a technical error .... I used ISO 100 to keep the sky black, and f/11 to give a fairly wide DOF to shots that spread out over the horizon, with a probability that some were nearer and some farther away from my shooting position. Upon reflection, I agree with Larrie that a wider aperture may be the way to go to let in a bit more light. I shot last year at f/8, but am thinking of f/7 for the next fireworks display.
