Does anyone have a good starting setup for running the X10 2018 in WGT-R on black carpet?

Using the supplied 96T spur, what pinion range can you run? I'm worried I may not be able to get a large enough pinion on. I was running a smaller spur on my CRC. (Motiv MC2 17.5 on 1S). Anyone else's spur gears work on the X10?

I'm ditching my CRC Gen-X 10R/T for an X10 to accompany my X1.
