hmmm, how to answer this question.
I have had different feelings about the HO over my almost 2yrs on my 2nd AH career. I HATE them, they are lame and seriously a waste of both individuals time. Some seem to be just fine with wasting their time though.
It depends on the bird I'm in and the situation I've put myself in for me to make the decision to avoid, pretend to avoid, go guns blazing or give a feint with some pepper to fool.
Cannon birds are a bad choice to try to HO if you have 50's; vice versa. To make matters worse, there are some sticks good enough to give a HO attempt and still make a decent acm to your disadvantages.
Bottom line is you need to make the decision for yourself and all situations are different, in one instance may not apply to another.
Some are going to tell you they are completely avoidable and takes two to HO; nonsense. When you are engaged with multiples, it only takes one determined (paraphrased from Dolby) HO'r to ruin it.
If I see someone make the effort to point their nose right at me instead of set up a post merge move, then I begin to make different decisions.
Don't HO though, I think it only begets more.
