Head on attacks are the best. To me, there is nothing better than seeing some dweeb point right at me, intent on carrying through an HO.
Simply wait untill the last second, pull up hard into an immelman before you pass, and come down on top of said dweeb. Even if he matched my turn, I started it well before he did, and end up with the advantage. If you go head on with someone, and they don't want to take a gunshot with you, you'd better kill them. If you don't you just blew the initiative.
Always remember, It takes TWO to HO. You may run into someone who won't do anything but fly straight at you.(Damn him for not surrendering to you!) If you join in for the gunshot you take your chances. Or you can use thier HO fixation to your advantage.
Never mind that HO attacks are historical. The US Navy F4F's used a maneuver called the thatch weave, which would force repeated HO passes against the japanese zeros who, being outgunned, would be wary of such an attack.
Anyways, whining about any potential fix for Ho attacks, or saying why we shouldn't get one is redundant. It's a bit like the argument about why we shouldn't have an abomb. There is no point to it, since it's not going to happen anyways.
