Train as you would fight. Ha!
4v bounce - Yes Fun, but little 'tactical training' benefit when it comes to night IMC low level (night one strike one). Unfortunately, if you do not have the low level peacetime airspace to do a 'real' simulated sortie, you must rely on your pre war 'work-up' to get in good shape.
As to airfield denial, there are equally effective methods of achieving same result (by result - I mean keeping enemy aircraft on ground) without having to do the straight and level thing. Unfortunately if the designers give you a weapon that can do only one thing, you have to get used to going to the gunfight with someone else's spurs fitted.
