found that with a short sling, whirling the thing about
first was counterproductive, and favoured the single
swipe, which many others use too. It is possible to
whirl it round far faster than one can cope with when
it comes to releasing the stone. As the movie clip files
show, I throw my whole body weight into the shot, and
spring off my back leg. Also, by bringing my arm not
quite to the vertical, but a little off to my right,
I am able to use a strong combination of muscle groups,
much like one is taught to throw a javelin in athletics.
