Best way to get something out of this session, is to have him do it with 3 or more others, let him do a few alone at first, then send him with the others, couple behind or a couple in front, one alongside, get him to focus on the hurdles with horses around him as doing it alone is a different ballgame to what he'll face in the CH, knowing his issues if he lined up, and I was riding against him, I'd be doing all I could to unsettle him cause that'd be my job, take every advantage you can & try to win hence wanting him jumping amongst horses before the day.
