I love that rollback one... and agree with you on the trust. It takes a lot of work, but it is soooooo worth it!
My mare came to me afraid with no trust, and now I can wrap her lead around her neck and she'll follow me around campus without me holding it...It's a great example to the students here, too, because they have all experienced the opposite style of horse training...the 'breakin 'em in style'... They aren't used to methods that aim for respect through trust.
