For the gear diff, I've done some reading of the old thread, and it seems most agree that 5000cst is a bit thick. So is 3000, 2000 and 1000.

I had 3000, so that's what I put in mine the other night, but haven't run it yet.
Consensus seems to be somewhere around 50-80wt. shock oil instead. The two fluids aren't measured the same way, so they're not that different, viscosity wise. I don't remember where I saw it, but I believe 500cst is about the same as 70wt.
I have not tried lower then 5000 but I cant imagine wanting it any thinner.
I have a HW 10.5 combo and it can drift down the front straight at full tilt if I went even thinner I would be sitting doing doughnuts the entire race.
