The ProFly by Duncan is a rebranded version of the older ProYo II GT. It is essentially the same as the original Playmaxx version, but with new pog designs made by Duncan. The responsiveness of the wooden axle sleeve makes it good for looping, but not too good for string tricks, despite the Butterfly-shaped body. It was also released in the 2003-2004 iteration of the Hyper Yo-Yo line as the Hyper Loop Fly (Japanese: ハイパーループフライ), of which a hand-painted version by John Higby, known as the Hyper Yodel (Japanese: ハイパーヨーデル), was also released.
