Head on only works if the enemy wants to go head on for one, and you're at least sure you can do some good with it. But usually it's a lottery. Frankly I'd advise against it because it's a sudden-death situation and you have as much chance of getting shot down as you are of shooting the other guy down. With the increased closure rates and bullets hitting largely unprotected parts at the front, you're looking at possibly instant fatal damage. Besides, the smart thing to do when you're closing head on is to slice - begin turning before you pass the enemy so that you have a head start on the turn after you pass and can get on his tail quickly.
