Ah, the old "head-on" or HO argument. If you search, you'll find many heated threads on that one here.
Remember too that netlag plays a role in this.
You may be thinking "oh, no.. another HO shooter!" while the other guy is thinking "ah, a perfect front-quarter deflection shot!" Netlag once again.
Also, don't think that HO's weren't taken in WW2. If they had a shot, they took it. Just read an autobiography of a local P-47/P-51 ace and he mentions taking a head-on shot at FW's in two different engagements.
Besides, if you are anywhere close to corner speed, a HO shooter (and even a front-quarter deflection shooter) is pretty easy to avoid.
If you are significantly below corner, however, you may have to make the best of a bad situation and take a shot yourself.
Again, my .02 and after THIS bit, I'm sure the arguments will start.
So... (vrooom) I'm runnning for the door in this thread!
