When Doctor Popular received a ProJam prototype for evaluation, he chose O-rings instead of starbursts for the Bolt's response system. The available colors were red, orange, and blue. It was also offered in a textured and silicone-recessed version.
DocPop himself had also encouraged modding on the yo-yo and even provided instructions online for it.
