Do you guys think there's any difference between steel pinions made by different companies? Are any brands more precisely machined than others or are any made out of higher quality steel?

I know mod 1 should be mod 1 but I'm just curious. I don't even know what brand I'm running since I bought a 3 pack from the LHS when I bought my RC8.2e. I just know I'm running 16t on my ET48 and 17 on my EB48.2.

Any that seem to run quieter than others? My truggy seems to have more gear noise than some others out there. It's not loud like the RTR cars seem to be but it makes me think a higher quality pinion might be a good thing.

I'm running the stock plastic spur.
