how strict is the no hands rule? For spinning tricks only? What about that eclipse variation trick where you put the ball between your hand and your foot and jump over the ball? And what is the penalty for using your hands too much? A points deduction or something? 
The hand rule will be quite strict, but we will leave also the judges appreciation whether they feel they have to deduct points or not.
We just want the League not mix between football and basketball and really keep the hands for very specific tricks. If the hand is used for recovery or used too much during teh battle, it will be penalized.
Of course the rule will get clearer when the events start and we can somehow have a feedback from judges and from the 1st events experiment.
