Ok so update on the bitless. After riding bitless several rides over a couple weeks, his flat work has improved SO much. He trots around on a loose rein with his head down and can lengthen or collect his stride pretty easily when asked. His canter is also much better, he doesnt suddenly speed up anymore and he keeps a calm consistent pace (still a bug stride for a small horse). I didnt see much improvement with him rushing to jumps though so that is still a work in progress. Thank you so much for all the help and advice.
