Something I have either skimmed over and just missed the reasoning or haven't even thought about it before now.

What is the different between the adjustment nut assembly on the E-Revo and Revo Slipper units?
E model uses the spring retention and the Nitro version uses those 2 cone washers.

I'm wondering because I'm running Mod1 gearing on ERBE/EMBE transmissions in my builds.
Should I be using one or the other?

Not sure why I'm thinking about this all of a sudden, i have some HR Double up units on the way so I'm revisiting the Slippers on my ERBE, ERBE-GT, E-SlayerPro4x4 (might as well do em all right )
