Changing Bowls
Most of the important information concerned with either using different sets of bowls, changing bowls or delivering the wrong bowls is covered here.
Trial ends: According to the laws of the game a player can use any legal bowls, from different sets, for the trial ends. The trial ends are not ‘the game’. So, a player can ‘try out’ their various bowls during trial ends, but, can only deliver the agreed number of bowls. So if it is 2 bowls for trial ends in each direction, only 2 bowls can be used each end, from any set.
The Law:
5.1 Trial ends
5.1.4 Each player must not use more than the number of bowls being used during the game. If a player or an umpire notices that a player is using more than the permitted number of bowls, the defaulting player will lose the right to play any bowls remaining to be played in the trial ends.
5.1.5 Each player can use any combination of bowls taken from different sets of bowls
This is why trial ends are important, if playing at familiar or unfamiliar venue. Players can work out the conditions, and either by using just one set of bowls or a couple of set of bowls for trial ends it helps players work out how the green is playing. Trial ends are important, and must be used. ‘One on the first two ends’ (which is rarely a written law in a competition or league) is a disadvantage to both teams. Agreeing to it at your home venue could be costing you shots, because your opposition will only lose a maximum of 1 shot in each of the first 2 ends, where potentially (and more likely) they would lose more than a shot during the first couple of ends on an unfamilar green. So tactically, it is better to agree to ‘one on the first two’ away from home, but ideally trial ends are a better option at home and on unfamiliar venues.
According to the laws of the game a player must use legal bowls, from THE SAME set, during ‘the game’.
