Ahhh the HO debate.
My position on this has never changed and never will. IF you are in my gun sights I WILL fire. If you are going away from me I am some kind of fighter combat hero, heading towards me I am some kind of fighter combat villain!! I see no difference - my guns point at your plane - automatic reaction to pull trigger.
Now of course there is a risk / reward factor in this. If you are in a cannon equipped plane and I am in my P51 - I am not going to go for this. It is 50 / 50 at best, against canon planes it is more likely 80/20 in their favour. HOWEVER, I can usually (90%) of the time make a call to avoid the HO way before the enemy is within guns range. The only time that is not true is in gang bang fights - and yes, HO is essential - take every shot you can.
So, to HO or not to HO - you call it. If I think I have a better than 50/50 I WILL take the HO - It is a scoring shot and that is what we are here for. The 'dance' is a nice bonus but the kill is what we must strive for before all other goals.
