Why do you recommend the blue rotor instead of the green? I have been reading in the 1/12 thread and was told green is the way to go.

Second, where can you get a 70 spur? I run an X12 and I have to run a 74. 72 are never in stock from precision and I have not seen a 70. Tried a 72 from CRC but diff would not tighten up, and yes I also bought new diff balls since it uses smaller ones. Thanks
