I am slowly building up to lead changes with Traviata. We started by just cantering and then trotting for a few strides before asking for the other lead and then eventually we just trotted for three steps. We're trying to minimize it to one step before asking for a flying change. Traviata has kind of figured out that she should be on the right lead so if we're doing a course and I tell her to trot then canters again with just a cluck. I few times she's actually done a flying change but she tends to buck after then so we're working on keeping the couple of trot steps. Eventually we'll get it but it's a long way off. I'll just have to keep trying.
