I have also wondered about this training. I was following the Clinton Anderson training and found that his Handy Stick aka Carrot Stick was great for desensitizing but when I whack my arab mare with it or try to lunge for respect she turns on me. I can disengage her hind quarters with my thumb, but the stick makes her mad at me for whacking her. I did get some training aspects from this, though and my friend swears by it. My girl did much better under Gawanni Pony Boy training, she follows me everywhere, now that, she respond to, no sticks or gimmicks just bonding and letting her know what I want, I use my body language, hands and ropes, Simple. It, I guess depends on the horse, and my girl won't have it. You want natural go Native, wether eastern or american, I find great things in both, watch Ali Al-Ameri (you tube)he's awesome.
