I am finding this thread very interesting. I can't say one way or the other how I feel about it because I'm no where near being that accomplished of a rider. However, having said that, I try to ride in a way that makes my horse a partner, and not having him submitting because he's afraid not to. I'm turning a former jumper into a dressage horse. And we've had to start at square one with him. I'm finding that if I try to force ANYTHING with him, he's throwing a fit (not that it happens often, or at all anymore). Just cannot force him. But rather, if I work him slowly, and with understanding, he responds beautifully, and will do just about anything I ask.
I see both sides, and while I think anyone below a certain level of riding attempting to use hyperflexion/LDR would be disastrous and ineffective, who knows? I certainly can't say. I'll just stick with what I know, and what's working, and see how far Zeus and I can get. I'm going to worry about my own horse, my own riding, read the debates, learn, but not make any judgment that I'm not qualified enough to make.
I give myself very good advice, But I very seldom follow it
