The basic differences are weight and durability. The Super Swirl and Super Star are the same disc, aside from cosmetic changes, and the new bottom dyed Super Swirls have patterns on the bottom of the disc. With feedback from many competitors who draw on the bottom of their discs to help the dog zero in on it in flight, Hero has started testing a bottom dye disc. Weighing in at about 130 grams, the Super Swirls and Super Stars are a bit softer than the Super Hero and very close in durability and puncture resistance. The Super Hero is the flagship disc for durability, puncture resistance and eye catching colors. Weighing in at approximately 136 grams, this disc is the strongest one we make and is guaranteed to allow more playing time with your furry teammate. If you have a dog who is tough on discs, this is the disc for you!!
