Renegadesignlab (RDL), triangle and square rings? These "rings" are a new development for manipulation. They are pretty hard to juggle and need to be thrown like clubs with an accurate number of spins. Most of the routines so far have been less toss juggling and more contact/isolation manipulation. But regardless, if you are interested in something new (with undiscovered tricks) a few squares or triangle rings might just be what you are looking for!
