Have you seen the Olympia video clip on the main H&H site? It's much better than the one they had last week for Cheltenham, although it did make me feel a little seasick in places
According to the bit in the magazine it was taken by one of the H&H staff members jumping round the celebrity ride and drive class so I don't suppose they had any choice over what height the jumps were. I agree that it would be good if they could get a top rider to wear it over a bigger course.
