It does not matter which one you use. The scaling is the same. The only thing that changes is you get 4x the resolution when you choose k4x.

Yes. That year we used the VexPro Ball Shifters. There was a 3:1 ratio between the encoder and the shaft. http://www.vexrobotics.com/vexpro/mo.../217-1718.html
