If you use a double, it should be short and fast.
Doubles look far better.
This is thrown just like a chop pass to your partner, which is held like a hammer, with your thumb pressing on the club handle to guide it. Do not choke up on the club, because the knob would bump into the back of your hand. To add flash to this trick, throw every other right hand club overhead to your left hand, alternating with your passes. Furthermore, you can get down on one knee, which looks interesting. After a series of these on one knee, make your last pass a shoulder throw at the same time as you rise up to standing position again.
