I like CA. I think there are a lot of trainers out there that are phenomenal at training horses, but have difficulty teaching it to people. CA is one of those trainers that makes sense to me. I can take something I watch him teach on a DVD, go put and try it on 10 different horses, and it always works. Selma horses take longer than others, but it always, so far, has made a huge positive impact. I'm on a kick right now where I'm getting his DVDs from giddyupflix.com. (There's absolutely no way I could afford to buy the DVDs) I'm getting about one a week, trying it on all the horses I work, and it's making a big difference. From 4 year old green horses to my 17 year old finished reining horse that could use some brushing up. So, that's just my personal experience.
