Here's the deal on me and ganchos.
My free leg technique isn't pro level.
We are never likely to be going fast enough or to have enough momentum for my foot to swing up high as a natural movement. There's always - always - a tedious moment of standing still and thinking “oh, here comes a tedious trick to make us both look silly” before it happens. I think, and I get bored, very fast under certain conditions. It loses the flow completely.
I've been taught to fake them quite well (I was taught to turn the leg slightly so the heel goes towards him, and to swing rather than kick or hold) but it's a completely voluntary movement. This, I think, is what most people do, and it's certainly what I do after the wait for positioning is over, the reveille has stopped sounding, and I get some sort of a lead.
I'll usually fake it at least once, as long as the man hasn't done too many other things to annoy me. If it's once in a tanda, the man dances with real feeling for the music (that is, having some apparent sense of the melody and phrasing and at least the most obvious emotional content, as opposed to just being on the beat), and it's in the right place, then, okay. At least then there are other reasons to do it, beyond whatever version there is of a lead.
If I don't really intend to ever dance with him again, I can fake cheerfully because it's just the once. It depends. If there's anything else so seriously wrong that I don't care if it annoys him, I probably won't fake. I'll just stand there and smile and pretend not to understand if he starts talking.
If he were a friend, I might fake for the sake of peace or the conversation. But in strict moderation.
Basically the reason I don't like them is that my limitations, quite apart from the difficulty of the lead, make them insincere, and I prefer to dance sincerely. That movement isn't something I would ever spontaneously do to express tango music, and it isn't something I would naturally do in response to even the best of leads that actually happen in reality in social dancing. It requires a higher level of technique than is going to happen. I don't like my moment being killed, and I don't like faking.
I prefer what I am doing when I dance to be faithful to a reasonably consistent overall aesthetic concept, and that means not faking things. That's just the way it works for me.
