Each person will be able to purchase a throw.  This can be used at any time, except for a putt, and only one can be used  on a hole.  This would take the place of a stroke.

Example:  The team is 20 yards out from the green .  The other players can chip up onto the green and the person with the throw, can choose to throw the ball.  If the ball lands closer to the hole from the throw, then there is no stroke for the throw.  If not, then play continues as normal and that player's throw has been used.
