bitless flexions

I've been teaching Chapiro the rein actions for some time now and almost gave up when I went to Di's and felt Rem's mouth in a bit! I want the same feel bitless of the neck yielding and the mouth being mobile but Chapsi is a stresshead and keeping it all mobile has proved diffeicult. The last couple of days we've had a bit of a breakthrough and the boy has been chewing and swallowing during the flexion work. Next will be to try and transfer it to ridden. It's still not the finished product but here's the video from yesterday.
