Thank you all. By way of update I’ve hacked him since (with our one reliable friend) and he was fine. He’s still in his myler comfort snaffle. I spent the whole ride shaking so need to get my confidence back up when out. I’ve mostly gone back to working on the other issues. His new saddle has arrived finally. He’s still bucking in it but other than that going really well. There’s always so much to learn and to do with him.
