On Edward Gal for a moment now that you mention him - I have seem two sides. Yes, I've seen the video's of him employing rolkur as a training technique, I've seen the photo's of his horses's heads cranked to their chests in draw reins with spurs strongly engaged, but I've also seen him ride amazingly kindly, so quiet, such beautiful, soft, un-interfering hands and a sensational seat.
He was in Australia for a Masterclass at the end of 2011 - and there we again, saw the soft, kind, sympathetic, brilliantly effective side of Edwards Gal's riding, along with partner Hans Peter Minderhoud who was also a stunningly sympathetic rider, with a strong focus on developing very solid basics.
That said, we've also had Anky do a Masterclass here about 8 years ago, and she too, was wonderfully sympathetic and really pushed the 'happy athlete'. Didn't see a single amount of rolkur produced at any time. Her partner Sjef, was an incredibly friendly, down to earth individual that was willing to take time out of their very busy schedule to talk to anyone who wanted to discuss any training issues with him. He would sit down and talk through everything.
Ulla was the one Australia kicked out and told to never come back. We had horses literally wrecked after clinics with her. One become so distressed, that it bolted straight into the side of the indoor arena, flipped over the side and sustained massive injuries as well as severe neurological complications that took years of dedication and patient training to settle.
