I seldom try for HO attacks. It is better to manuver and get a better angle to attack from.
If I am at an angle disadvantage or want to even the angles, I most often go for a "HO Merge". Which is not the same to me as a "HO Attack". I "Turn Into" the attacking plane. Because of heightened SA, due to game play concessions, this happens frequetly.
IMO this is better than giving up angles from the "Get Go", by steering clear of "HO Merges".
When a HO is un-voidable, I manuver to force an oversteer. By faking a HO pass, I might get the NME more focused on a HO kill and less focussed on the angles they are giving up. It is often "Win the Merge, Win the Fight".
However, I almost always shoot during HO's if the seperation is close. Hopefully, I can get a fast rudder kick in and make some hits. It makes them think about dodging and I might get lucky. From my experience, HO's are ussually 30/30/40. Where 30% you win, 30% you lose or 40% you both lose (both get shot down - one gets the kill).
I am much more concerned with not getting shot down and setting up my merge angles, than I am with scoring a HO kill.My strategy changes for an ongoin fight, depending on comparitive E states, other NME around, how I am doing at angles or what my confidence level of winning the fight is. Sometimes you just have to take your chances.
Good Luck in the Unfriendly Skies!
