I went a long time not HO-ing in my P-39 because of the 'ettiquet'. 70% of the time, the guy hoed me, and I wondered why I didn't shoot first when I saw him lining me up. The other 30% of the guys that don't shoot are probably veterans enough to know the ettiquet which means they are veterans enough to kill me.
. In which case I need the advantage of making them break early. So I made the decision about 1 month ago that if someone flies staight at my P-39 he's going to get a face full of 37mm. 
...better break early.

I've never come across this "HO etiquette" rule in any of the 4-5 Combat Air Sims I've played over the years. Strange. Almost a left over of medieval jousting - certainly not based on any sort of 20 Century combat concepts. <shrug> maybe many of the people complaining should really just limit themselves to the DA - it seems they would certainly be a lot happier and not feel so put upon. Just MHO.
I fly a 190A8 exclusively as a Boom & Zoom fighter - as IMO it was intended to be fought. In a large majority of my attacks I would estimate that close to 60% of my cons turn into me and go Head On. It is human nature to want to face your enemy and get a few licks in as soon as you can. Maybe they intend to fire or break off - I have NO way of knowing and if I wait till D5 or less it is too late. As far as I'm concerned if a con is still HO at D12 he's committed to a gun run on me. I'm either going to "refuse" the HO or give him a face full of 20 mike mikes. MY choice and I'm certainly NOT going to whine and cry on 200 or PM as I see so many doing. Grow up and accept it.
What really irks me are the "You're playing the game wrong" "You'll never learn anything" "You're ruining it for others" Fightards whinning that goes on. It IS a part of the game and if YOU are so good at the game then what do YOU care if others do it.
Seems that it's usually the losers who whine - if you avoided the HO then what's the problem? According to Fightards the HO'ers are now in an inferior situation....go figure
...BUT these guys are so easy to wind up - it's almost criminal to do it .....um........naw......

I think they actually enjoy the whinning about HO's - otherwise they'd have to find something else. Xrist on a crutch - it's just a game!! <shrug>
...can't you fightards just learn to get along with everyone eh??
