I'd think you mean instead:
A) bigger spur with a bigger pinion
B) small spur with a small pinion
both of which give the same ratio?
There's an earlier thread from last month discussing same topic.
There was some opinion that (B) gives slightly better acceleration.

isn't there something like you want the smaller because it's less rotating mass? But I dont see how this would make a difference.

if you set your gear mesh vertically, a bigger combo will lower the CG(motor will be closer to the chassis), just depends on the car...

i've found yesterday the other thread that WC mentioned "Gearing Technique - Better Acceleration" ==> http://www.rctech.net/forum/showthre...oto=nextoldest
i think that they have covered quite substantively on this issue. another almost similar thread is "Final Drive Ratio " ==> http://www.rctech.net/forum/showthre...oto=nextoldest
perhaps any further discussion can be substantiated in those 2 threads. i'm sorry for creating a new one without searching thoroughly.

Makes your motor work less hard, so it eats less current.
But severely over-revving your motor due to gearing too low
will actually make it heat up more too...
