Another vote for the Manfrotto 680B, I've been using one now, for a good number of years for both sports and music/gig photography.
In addition I use the Manfrotto 234 Monopod Tilt Head, it just adds the additional plane of movement that I require in use, they also have quick release version 234RC available if required.
Also it collapses down small enough to fit suitcases when traveling, I wouldn't recommend hand luggage, as it has a shape similar enough on the x ray scanners to get you unwelcome attention.
