Try lunge work in a pessoa or similar device. My ex trotter is hard work to bring into an outline due to having been driven in an overcheck in his previous "career" and I find it easier if I use the pessoa prior to schooling him. I only need to do it occasionally, like if he hasn't been ridden much over the winter and is reverting back to his old ways, then he's ok again. i also have a pair of Carl Hester "fantastic elastic" reins which are quite good, but really it's about schooling issues.
