Hey Mark, I dont know if you've seen this before or if it really pertain's to your query b/c there's no mention of shock oil weight.
Plus no mention of your style of massive, Snake-River Canyon, Behemoth jumps. 
Nonetheless, I thought you may find it helpful.
This is from the UE site pertaining to the setup to the shocks you run.
From what we've seen so far running them on our racetrucks the blue one works best in the rear and the red in the front. On our 8 shock heavyweight Brushless E-Maxx we use 4 white in the front and 4 reds in the rear. Heavier (than our racetrucks) 4 shock trucks will find that the blacks in the rear and blues up front will work well.
Are you running the 8 shock set-up yet? I know this thread was a few weeks old.
