Yea we discussed this before... its old name is 4 poi, or 4 long poi (depending on length) I dig 4 poi but often it can get nasty dangerous.
For moves u should try 4 poi weave with wraps, like maybee try with 1 hand to do a weave and let 1 poi wrap over the arm that is spinning them, just for a single (thru) wrap, and it should come out when u change direction and then do that again the other direction.
Now once you can do that both hands same time on the sides of your body, you can start to do it in the weave (which u say u can already do) so should be easy for ya, and its alot eaiser than it sounds.

Traditionally butterflys and split time butter flyz are the norm with 4 poi, or even slightly off set times can look amazing.
