When I'm in the 190F-8 and already engaged with a bandit (and maybe still carrying ords for gv's below me), I HO on any second bandit that comes into the picture. Well, maybe I wouldn't do it against a Typhy, but it sure worked well against an LA-7 the other night.
Bottom line is, when faced with a faster, superior maneuvering aircraft, the head-on is de rigueur.

In bubi's defense, he's saying that turning the outcome of the merge into a coin-toss is no way to maximize your win %.
