I say HO away. Never mind that 99.9% of the people who cry about it can't tell the difference between an actual head-on (mutually-assured destruction) vs. a front-quarter shot (shooting someone from the front, but without risk of them being able to hit you due to their angle); rather, HO'ing brings out your opponent's true character and deepest emotions. It shows the difference between those that play to have fun and those that have some sort of deep-seated emotional investment tied to their losses.
For example, this past Saturday there was a rather poor P-47 pilot who came at me from below. Knowing his speed was too high, I pointed my nose inside of his projected flight path and waited. He pulled into me, allowing for a clean shot to the inboard side of his nose/wing root. Never mind that he didn't have a shot, or that he was being chased by numerous other aircraft, a Fugitive from justice as it were, and would have certainly died; no, he decided to spend the next 5 minutes raging on 200 about a "HO," as if that somehow validated his choices post-death.
I say HO to your heart's content and never look back!
Or it might show that they are getting really freaking tired of climbing to alt ~8mins flying to target ~3-5 only to be downed by a HO, repeat that once or twice and boom, customer lost. Even some of the long time heroes are sick of it and the new AH attitude of kill/score is the most important thing.
Skill is to be admired; k/d and gamey maneuver don't mean caca.
I see you speak of it quite a bit yourself.
