In the current line? Nothing in my opinion, maybe and I mean maybe a Furious with polish and a stronger pin. Even still, the core in the Furious is smooth and it would be hard to replicate the Rapid Fire motion. Maybe a shiny a Reign of Fire, but the core in that ball is way stronger than the Rapid Fire core. Tough call, but I think your best bet may be a Nomad Solid.
