I have over 70 people on my list in just three events. You can also have a six-wicket layout to show the differences between the two versions. It is best to use Forster Challenge sets or something similar because of the ease in putting in the wickets. Also bring your own tournament mallet and one tournament wicket - again for contrast. Let them play the version they are familiar with.
Breaks are unheard of to untrained nine-wicket players.
Once they see the different croquet shots and the patterns established in breaks, there will be a new-found respect for a version of the game they never knew existed. In fact, delayed triple peels can be accomplished. Yes, the courts have to be undersized, you will have to experiment and find the smoothest surface available, but it can be done - especially if you widen the wickets appropriately to compensate for the rough turf. Anyone who would like to be personally guided through this process is invited to E-mail me. I am passionate about promoting the sport to everyone who is interested.
