There was a similar discussion a few weeks/months ago on this topic.
I think the conclusion is to run as big as a spur if possible to move the motor forward for balance reason.
For me, I run in an outdoor track, so, I keep the spur to be small to increase the ground clearance for the gear. This is in case of small stones on the track.

I run Yokomo R12 which come with xenon spur. But I run Kimbrough because of the diff cover. Kimbrough spur can have a optional diff cover to protect again dirt so, I don't need to rebuild my diff often.
