You can run any 17.5 you like. Some people tune for a specific track by changing rotors, high RPM for a long fast track, high torque for a more technical layout. Standard rotors work just fine for 98% of people. The most popular right now seem to be the Revtech and the Trinity D3.5, but getting the set up of the chassis and the gearing right is much more important than the brand. Last Sunday at our track I think it was a Revtech 1ST, Speed Passion MMM 2ND, and D3.5 3RD.
