I drilled them at one of the Open House things storm had here in Charlotte, the rep said it's basically got the same core as the Street Rods I believe (light bulb with the bottom piece), but they've got the RSX covers on them. The Furious (the sanded one) hooks out the house. Stronger than the Virtual when I threw it, and a decent bit earlier. The Fast (pearlized), rolls really well and has a fairly strong backend but nothing uncontrollable. Can't beat these 2 for the price.
