The complete version is a real nightmare. Both passers MUST be extremely steady with four clubs. On the other hand, the theory is quite simple: each juggler starts with 4 clubs doubles (in the same time), then you throw a pass every 3 throw (double pass)
Each juggler should then do:

8 clubs, 3count, coming from 4 clubs solo
: <4p 4 4  4p 4 4>
Be careful : On the scheme, it starts with the pass 
If you feel really confident (or just for fun with JoePass!), you can try the
supercomplete version by replacing 2 double selfs in a row by triplesingle,
thus you get an 8club popcorn !!
You can notice that this rhythm (just like the following scheme) is a part of
a whole family: the rhythms taken from
4 clubs solo.
This one is much more easier, and you will use it as a practice for the whole version. It's all about throwing half of the passes: you pass only either the LH passes or the RH passes. It's in fact a 6count.
8 clubs, 6count popcorn: <4p 4 4 4 4 4  4p 4 4 4 4
4>
