However, there are several very athletic horses that can jump great heights with considerably poor bascule due to sheer power.
Some bascule is an important trait for all jumping horses, as it is more mechanically efficient for clearing high obstacles.
For example, drops are best jumped with little bascule, so that the landing is made as short as possible, putting less stress on the horse's legs and the rider's balance.
In the case of the steeplechase fence, it is detrimental for the horse to have a powerful, round jump, because it consumes time and energy.
In some cases, a more relaxed atmosphere or improved conditioning may help the horse to flex his spine better.
