Pro Set you get a "pig" (target ball) and two sets with 3 large balls. Initially, the pig is thrown from stehts location (where is the players of course optional). After that must be alternately tried their own balls as close as possible to place the target. It is however to be not just about the next special to achieve special combos (eg ball on pigs -> 5 points, contact with pigs -> 2 points; etc.) But of course you can also create your own scoring system. Make it a player his ball at an opponent's to bring lie, the ball lying down is not counted (ie so you can also annoy his teammates very well).
The material properties so far I find without hesitation. Unfortunately, I have had the balls for some time (1-2 weeks) are long in the sun. The result: In the sun-facing side is the black bit faded. So, always keep the best balls on a light protected location ;-)
Positive aspect is also that you have a huge variety of shapes and patterns with the balls and can thus choose the set that one really likes best. Also you can set this course easily combined.
We have tried Crossboule previously in different places, without some damage has taken: garden with a pond, in the house, in nature, in the city center (since the passers but something goofy geguggt); However, one should note that the target selection also means that you get back the balls again (if it go smoothly in the gutter of the most fun over)
