FAST 201 was the premier first release from Yoyofactory. It featured a completely new and unique response, Fully Active Starburst Technology, F.A.S.T. Starburst response could be adjusted, and less response the faster the spin. The clear outer shells show the response spring, which came in several colors, grey, yellow, blue. Profile and Response views show a yellow spring.
