I have decided that nothing can win this race. I'll still need to have a bet in it though. The Pipes don't tend to tilt at windmills, in which case Western Warhorse is overpriced.
Seriously, Western Warhorse is a wonderful sight to see jumping. He is an nutcase and as likely to refuse to race as he is to win, but if he jumps off, he will attack every fence and be a joy to watch. He would have an each-way squeak IMO.
