I like to use all of my gas in the training area too instead of saving an extra 1,000#s for being dash 4 on a TCN or PAR approach. The overhead aopproach allows a number of aircraft to arrive at the field and get on deck in a quicker and more efficient manner - thus saving time and fuel and in some instances - it is tactically viable. I'll agree with everyone else too that it is just more fun that the 10 mile visual.
