I was wondering if there was any difference in running a larger or small spur gear. Would there be a difference between an 104 or an 116 if they both rolled out the same?
Short answer is no, there will be no noticeable difference.
If you want to read many pages of opinion and arguing on this subject there was a long thread on this awhile back that you can find with the search feature.
save your self the hastle, Just try the two different gears on the track and see for yourself. you'll read that post and be there for hours.........I've been in your shoes. I noticed no big difference
