Anything that isn't Storm or Roto Grip is going to be at least earlier than your Rapid Fire. Without getting too far away you could look at a Columbia Noize, or Arch Rival. Ebonite has the Gamebreaker, but it would be quite a bit more. Hammer has the Anger and BW Bite. Track would be limited to the Rising.
As far as a pearl, you could go with an Ebonite Playmaker, or Hammer BW pearl. You might want to be cautious because if you go with something like a Momentum it might seem weaker because it hooks throughout more of the lane than your Storm stuff does.
