I too have no respect for someone who head fakes like he's not going to HO but instead go for a conventional merge then pulls for a HO at the last second. To me that indicates a person who doesn't really want to fight, but not only that, is so insecure about the HO crapshoot he doesn't want to pre-emptively telegraph his intention to HO for fear of reciprocation from someone who may have better aim/luck... So, in a way, he is worse than the pure Ho-rat.
My personal philosophy is this. I enjoy fights I love to fight but if I have no other viable option I will HO. There are occasions where the correct move is to HO. An example would be on a rope where the great climbing turny plane has just enough E left to nose up and spray in your direction as you are coming over the top for a shot. In that situation you have gravity assist on your side and he has gravity fighting him causing his nose to bounce all over. In that situation you almost always want to take that HO rather than blowing some more E relative to him to try for a more favorable attack position. Another situation where HO'ing is the right move is if you're engaged with a lightly armed plane like the fm2 or p51b who is determined to sacrafice E/angles for the HO and you are in a heavy cannon plane with little or no opportunity to manuever for a rear quarter shot. I'll almost always olidge that type.
Generally speaking, someone who has other viable options, especially in a co-alt/co-e same plane encounter, but still HO's, is devoid of imagination, totally inept, or stupid, or some combination of those three. Why would anyone gamble 50/50 when they could fight unless they believe their chance of winning an even fight is less than 50/50, which is a self-admission they suck. By taking the HO in those situations, they guarentee they will always suck and never improve...
