Yes,
That would be the one. It is actually purple/gold as you stated. Upon it's release it was called the purple/yellow. And yes it is a particle. Mine is drilled basically label leverage which is supposed to create a more arcing reaction. However others who have thrown this ball claim to have witnessed a simular reaction. Not sure if I would call it a control ball but it does not appear to have a skid-snap type reaction. It makes a very strong readable turn that continues right through the rack, given the head condition is not too dry. I am still testing mine. That is why I am yet to post a review on it.
