Hey im sorry I got carried away and really didnt answer your question . Yes I've done some recearch over the years on the native american horsemanship only not by videos or such . I've readbooks on the subject and talk to several folks in person on this subject. IM a bit older then most on this site but still find so much great training information here as well as great fellowship and compassion from all on here . But back to your question it is a very good aid to use with your own methods when training your horse or just refreshing your self and your horse. I stated I just purchased my first videos on hose training which is very true . My wife got me the videos so I could see what her aunt and granny and some of her friends were raveing about. I've just finished watching the join up one from Montie roberts and it is cool as well as a couple others she has purchased me. But what really struck my interest was that they all state about the same things , when it comes to training your horse and that is common sense and knowing your horse watching your horse and being a friend to him or her first and formost, and yes I do use some of there methods to train my horses and that is so very funny since I have just watched my first vedios of there training ways . And have been training and rideing my own horses for a lot of years . And also gentleing horses for other people over the years also, which brings it all back to my first thoughts on training methods use them as an aid to your own methods of training but always make it fun for you and your horse know your horse watch them while they play and watch them even cloaser as you ride or lunge them and adjust what you do with the help from the trainers to your horse and your dself but mast of all enjoy the horse and ride them learn from them and they will in turn learn from you sorry about just running on here it just a horse thing with me Dave
