A staff (20) Having a paddle (18) mounted at each end of the staff with each paddle providing a generally planar surface (28) for hitting a ball (16) or other missile is provided for playing a sport or game. Between two spaced apart hand grip portions (22) of the staff there is a middle part (24) that provides at least one additional generally planar surface (38) for hitting the missile. The paddles may be hollow to reduce their weight and, in an alternative embodiment, permit the respective ends of the staff, to be telescoped into the paddles to adjust the length of the staff exposed between the paddles.

A configurable butt for a cue stick comprising a body comprising an elongate chamber having an internal thread and a movable weight coaxially located within the elongate chamber and having an external thread, the movable weight being threadingly coupled to the internal thread of the elongate chamber. An internal shaft extends through the movable weight is adapted to rotate the movable weight within the internally threaded chamber thereby causing the movable weight to move between respective ends of the elongate chamber by virtue of the threaded coupling for adjusting a centre of gravity of the cue stick. An indicator arrangement is coupled to the internal shaft and adapted to provide an indicate of the location of the movable weight within the elongate chamber.
