I filled the diff but now after a couple batteries it feels a lot like the stock build.
I too run on a small tight track(sometimes a larger one as well) and opted to move to a 3.5k Losi diff fluid blend against advice(from RCtech) that it will just leak out in no time flat. Well, folks it's been four packs(80min) and not one drip so far. Don't overfill it/fill it to the brim and it won't leak IMO. I reused the gasket as well.
I've left the dampers alone since I got the truck... but I did buy 25, 30 and 35Wt AE oil. As I recall it comes with 30Wt. Does one generally find that the damper build on an RTR is done competently or should I just go ahead and rebuild all four dampers?
For your track, I expect stock 30wt should do well especially if it doesn't have any real jumps as you say. If it's not broke, don't fix it eh? As long as your rebound is set appropriately and your not finding oil residue after every run you're good.
