I find that the problem with ganchos isn't just the yanking back, but that it just isn't possible to perform the hooking action unless the leader's leg is in exactly the right place in relation to mine. So I get the (slightly farcical) situation of me knowing I've received the lead for a gancho but being unable (and most certainly unwilling, in those circumstances) to carry it out. Also, ganchos take time for a novice lead to set up, so by the time it's been accomplished the musical moment has passed, making them a particularly unmusical move, IMO. They seem to be a favourite move with guys who are keen to manage a move that looks flashy but who are rather insensitive to the music. Or am I just unlucky?
