Thanks Gidji, I'm very proud of him, he's going great guns at the moment. I started working on turn on the haunches with him today, he picked it up within 2 attempts and after that would give me as many steps as I asked for, and even started having a play in travers on a 20m circle in trot! He's just a smart cookie :P
He doesn't usually suck back, he's just unfit at the moment and when he gets tired he drops back behind the bridle, usually he sits up in the contact and I can put his head/neck wherever I want it.
To tell you the truth, my coach didn't think we'd be able to get him to stretch into the bridle and swing for at least a few months... it took 2 weeks haha! He went from an ottb that braced his head/neck and had no movement in his back at all, to working sweetly into my hands and swinging that back. All it took was a lot of coaxing, sending him forward, millions of trot-walk-trot transitions making sure he was straight, balanced and forward throughout, and working him slightly counter flexed, then correctly flexed, then counter flexed etc. until he worked out that he wasn't going to fall over if he stretched out and trusted that he wasn't going to get his back teeth ripped out by me! As soon as he finally released the tension in his neck and back, he works like that all the time, very rarely in a ride is he above the bit and hollow now.
Plus I'd hope I've got him working alright, I've ridden that many horses now and am on the state squad lol, would be a bit problematic if I couldn't ride him well enough to start getting him round :P
